spack-python: remove superfluous /usr/bin/env (#44724)

Not sure why I had this here, as `/bin/sh` will find the first spack in `PATH` just like
`env`.

- [x] remove `/usr/bin/env` and avoid an extra process launch.

-# v0.22.0 (2024-05-12)
-
-`v0.22.0` is a major feature release.
-
-## Features in this release
-
-1. **Compiler dependencies**
-
-    We are in the process of making compilers proper dependencies in Spack, and a number
-    of changes in `v0.22` support that effort. You may notice nodes in your dependency
-    graphs for compiler runtime libraries like `gcc-runtime` or `libgfortran`, and you
-    may notice that Spack graphs now include `libc`. We've also begun moving compiler
-    configuration from `compilers.yaml` to `packages.yaml` to make it consistent with
-    other externals. We are trying to do this with the least disruption possible, so
-    your existing `compilers.yaml` files should still work. We expect to be done with
-    this transition by the `v0.23` release in November.
-
-    * #41104: Packages compiled with `%gcc` on Linux, macOS and FreeBSD now depend on a
-      new package `gcc-runtime`, which contains a copy of the shared compiler runtime
-      libraries. This enables gcc runtime libraries to be installed and relocated when
-      using a build cache. When building minimal Spack-generated container images it is
-      no longer necessary to install libgfortran, libgomp etc. using the system package
-      manager.
-
-    * #42062: Packages compiled with `%oneapi` now depend on a new package
-      `intel-oneapi-runtime`. This is similar to `gcc-runtime`, and the runtimes can
-      provide virtuals and compilers can inject dependencies on virtuals into compiled
-      packages. This allows us to model library soname compatibility and allows
-      compilers like `%oneapi` to provide virtuals like `sycl` (which can also be
-      provided by standalone libraries). Note that until we have an agreement in place
-      with intel, Intel packages are marked `redistribute(source=False, binary=False)`
-      and must be downloaded outside of Spack.
-
-    * #43272: changes to the optimization criteria of the solver improve the hit-rate of
-      buildcaches by a fair amount. The solver more relaxed compatibility rules and will
-      not try to strictly match compilers or targets of reused specs. Users can still
-      enforce the previous strict behavior with `require:` sections in `packages.yaml`.
-      Note that to enforce correct linking, Spack will *not* reuse old `%gcc` and
-      `%oneapi` specs that do not have the runtime libraries as a dependency.
-
-    * #43539: Spack will reuse specs built with compilers that are *not* explicitly
-      configured in `compilers.yaml`. Because we can now keep runtime libraries in build
-      cache, we do not require you to also have a local configured compiler to *use* the
-      runtime libraries. This improves reuse in buildcaches and avoids conflicts with OS
-      updates that happen underneath Spack.
-
-    * #43190: binary compatibility on `linux` is now based on the `libc` version,
-      instead of on the `os` tag. Spack builds now detect the host `libc` (`glibc` or
-      `musl`) and add it as an implicit external node in the dependency graph. Binaries
-      with a `libc` with the same name and a version less than or equal to that of the
-      detected `libc` can be reused. This is only on `linux`, not `macos` or `Windows`.
-
-    * #43464: each package that can provide a compiler is now detectable using `spack
-      external find`. External packages defining compiler paths are effectively used as
-      compilers, and `spack external find -t compiler` can be used as a substitute for
-      `spack compiler find`. More details on this transition are in
-      [the docs](https://spack.readthedocs.io/en/latest/getting_started.html#manual-compiler-configuration)
-
-2. **Improved `spack find` UI for Environments**
-
-   If you're working in an enviroment, you likely care about:
-
-   * What are the roots
-   * Which ones are installed / not installed
-   * What's been added that still needs to be concretized
-
-    We've tweaked `spack find` in environments to show this information much more
-    clearly. Installation status is shown next to each root, so you can see what is
-    installed. Roots are also shown in bold in the list of installed packages. There is
-    also a new option for `spack find -r` / `--only-roots` that will only show env
-    roots, if you don't want to look at all the installed specs.
-
-    More details in #42334.
-
-3. **Improved command-line string quoting**
-
-   We are making some breaking changes to how Spack parses specs on the CLI in order to
-   respect shell quoting instead of trying to fight it. If you (sadly) had to write
-   something like this on the command line:
-
-    ```
-    spack install zlib cflags=\"-O2 -g\"
-    ```
-
-    That will now result in an error, but you can now write what you probably expected
-    to work in the first place:
-
-    ```
-    spack install zlib cflags="-O2 -g"
-    ```
-
-    Quoted can also now include special characters, so you can supply flags like:
-
-    ```
-    spack intall zlib ldflags='-Wl,-rpath=$ORIGIN/_libs'
-    ```
-
-    To reduce ambiguity in parsing, we now require that you *not* put spaces around `=`
-    and `==` when for flags or variants. This would not have broken before but will now
-    result in an error:
-
-    ```
-    spack install zlib cflags = "-O2 -g"
-    ```
-
-    More details and discussion in #30634.
-
-4. **Revert default `spack install` behavior to `--reuse`**
-
-   We changed the default concretizer behavior from `--reuse` to `--reuse-deps` in
-   #30990 (in `v0.20`), which meant that *every* `spack install` invocation would
-   attempt to build a new version of the requested package / any environment roots.
-   While this is a common ask for *upgrading* and for *developer* workflows, we don't
-   think it should be the default for a package manager.
-
-   We are going to try to stick to this policy:
-   1. Prioritize reuse and build as little as possible by default.
-   2. Only upgrade or install duplicates if they are explicitly asked for, or if there
-      is a known security issue that necessitates an upgrade.
-
-   With the install command you now have three options:
-
-   * `--reuse` (default): reuse as many existing installations as possible.
-   * `--reuse-deps` / `--fresh-roots`: upgrade (freshen) roots but reuse dependencies if possible.
-   * `--fresh`: install fresh versions of requested packages (roots) and their dependencies.
-
-   We've also introduced `--fresh-roots` as an alias for `--reuse-deps` to make it more clear
-   that it may give you fresh versions. More details in #41302 and #43988.
-
-5. **More control over reused specs**
-
-   You can now control which packages to reuse and how. There is a new
-   `concretizer:reuse` config option, which accepts the following properties:
-
-   - `roots`: `true` to reuse roots, `false` to reuse just dependencies
-   - `exclude`: list of constraints used to select which specs *not* to reuse
-   - `include`: list of constraints used to select which specs *to* reuse
-   - `from`: list of sources for reused specs (some combination of `local`,
-     `buildcache`, or `external`)
-
-   For example, to reuse only specs compiled with GCC, you could write:
-
-   ```yaml
-   concretizer:
-      reuse:
-        roots: true
-        include:
-        - "%gcc"
-   ```
-
-   Or, if `openmpi` must be used from externals, and it must be the only external used:
-
-   ```yaml
-   concretizer:
-     reuse:
-       roots: true
-       from:
-       - type: local
-         exclude: ["openmpi"]
-       - type: buildcache
-         exclude: ["openmpi"]
-       - type: external
-         include: ["openmpi"]
-   ```
-
-6. **New `redistribute()` directive**
-
-   Some packages can't be redistributed in source or binary form. We need an explicit
-   way to say that in a package.
-
-   Now there is a `redistribute()` directive so that package authors can write:
-
-   ```python
-   class MyPackage(Package):
-       redistribute(source=False, binary=False)
-   ```
-
-   Like other directives, this works with `when=`:
-
-   ```python
-   class MyPackage(Package):
-       # 12.0 and higher are proprietary
-       redistribute(source=False, binary=False, when="@12.0:")
-
-       # can't redistribute when we depend on some proprietary dependency
-       redistribute(source=False, binary=False, when="^proprietary-dependency")
-   ```
-
-    More in #20185.
-
-7. **New `conflict:` and `prefer:` syntax for package preferences**
-
-   Previously, you could express conflicts and preferences in `packages.yaml` through
-   some contortions with `require:`:
-
-    ```yaml
-    packages:
-      zlib-ng:
-        require:
-        - one_of: ["%clang", "@:"]   # conflict on %clang
-        - any_of: ["+shared", "@:"]  # strong preference for +shared
-    ```
-
-    You can now use `require:` and `prefer:` for a much more readable configuration:
-
-    ```yaml
-    packages:
-      zlib-ng:
-        conflict:
-        - "%clang"
-        prefer:
-        - "+shared"
-    ```
-
-    See [the documentation](https://spack.readthedocs.io/en/latest/packages_yaml.html#conflicts-and-strong-preferences)
-    and #41832 for more details.
-
-8. **`include_concrete` in environments**
-
-   You may want to build on the *concrete* contents of another environment without
-   changing that environment.  You can now include the concrete specs from another
-   environment's `spack.lock` with `include_concrete`:
-
-   ```yaml
-      spack:
-        specs: []
-        concretizer:
-            unify: true
-        include_concrete:
-        - /path/to/environment1
-        - /path/to/environment2
-   ```
-
-   Now, when *this* environment is concretized, it will bring in the already concrete
-   specs from `environment1` and `environment2`, and build on top of them without
-   changing them. This is useful if you have phased deployments, where old deployments
-   should not be modified but you want to use as many of them as possible. More details
-   in #33768.
-
-9. **`python-venv` isolation**
-
-   Spack has unique requirements for Python because it:
-    1. installs every package in its own independent directory, and
-    2. allows users to register *external* python installations.
-
-   External installations may contain their own installed packages that can interfere
-   with Spack installations, and some distributions (Debian and Ubuntu) even change the
-   `sysconfig` in ways that alter the installation layout of installed Python packages
-   (e.g., with the addition of a `/local` prefix on Debian or Ubuntu). To isolate Spack
-   from these and other issues, we now insert a small `python-venv` package in between
-   `python` and packages that need to install Python code. This isolates Spack's build
-   environment, isolates Spack from any issues with an external python, and resolves a
-   large number of issues we've had with Python installations.
-
-   See #40773 for further details.

--------------
-Spack on Cray
--------------
-
-Spack differs slightly when used on a Cray system. The architecture spec
-can differentiate between the front-end and back-end processor and operating system.
-For example, on Edison at NERSC, the back-end target processor
-is "Ivy Bridge", so you can specify to use the back-end this way:
-
-.. code-block:: console
-
-   $ spack install zlib target=ivybridge
-
-You can also use the operating system to build against the back-end:
-
-.. code-block:: console
-
-   $ spack install zlib os=CNL10
-
-Notice that the name includes both the operating system name and the major
-version number concatenated together.
-
-Alternatively, if you want to build something for the front-end,
-you can specify the front-end target processor. The processor for a login node
-on Edison is "Sandy bridge" so we specify on the command line like so:
-
-.. code-block:: console
-
-   $ spack install zlib target=sandybridge
-
-And the front-end operating system is:
-
-.. code-block:: console
-
-   $ spack install zlib os=SuSE11
-
-^^^^^^^^^^^^^^^^^^^^^^^
-Cray compiler detection
-^^^^^^^^^^^^^^^^^^^^^^^
-
-Spack can detect compilers using two methods. For the front-end, we treat
-everything the same. The difference lies in back-end compiler detection.
-Back-end compiler detection is made via the Tcl module avail command.
-Once it detects the compiler it writes the appropriate PrgEnv and compiler
-module name to compilers.yaml and sets the paths to each compiler with Cray\'s
-compiler wrapper names (i.e. cc, CC, ftn). During build time, Spack will load
-the correct PrgEnv and compiler module and will call appropriate wrapper.
-
-The compilers.yaml config file will also differ. There is a
-modules section that is filled with the compiler's Programming Environment
-and module name. On other systems, this field is empty []:
-
-.. code-block:: yaml
-
-   - compiler:
-       modules:
-         - PrgEnv-intel
-         - intel/15.0.109
-
-As mentioned earlier, the compiler paths will look different on a Cray system.
-Since most compilers are invoked using cc, CC and ftn, the paths for each
-compiler are replaced with their respective Cray compiler wrapper names:
-
-.. code-block:: yaml
-
-     paths:
-       cc: cc
-       cxx: CC
-       f77: ftn
-       fc: ftn
-
-As opposed to an explicit path to the compiler executable. This allows Spack
-to call the Cray compiler wrappers during build time.
-
-For more on compiler configuration, check out :ref:`compiler-config`.
-
-Spack sets the default Cray link type to dynamic, to better match other
-other platforms. Individual packages can enable static linking (which is the
-default outside of Spack on cray systems) using the ``-static`` flag.
-
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-Setting defaults and using Cray modules
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-If you want to use default compilers for each PrgEnv and also be able
-to load cray external modules, you will need to set up a ``packages.yaml``.
-
-Here's an example of an external configuration for cray modules:
-
-.. code-block:: yaml
-
-   packages:
-     mpich:
-       externals:
-       - spec: "mpich@7.3.1%gcc@5.2.0 arch=cray_xc-haswell-CNL10"
-         modules:
-         - cray-mpich
-       - spec: "mpich@7.3.1%intel@16.0.0.109 arch=cray_xc-haswell-CNL10"
-         modules:
-         - cray-mpich
-     all:
-       providers:
-         mpi: [mpich]
-
-This tells Spack that for whatever package that depends on mpi, load the
-cray-mpich module into the environment. You can then be able to use whatever
-environment variables, libraries, etc, that are brought into the environment
-via module load.
-
-.. note::
-
-    For Cray-provided packages, it is best to use ``modules:`` instead of ``prefix:``
-    in ``packages.yaml``, because the Cray Programming Environment heavily relies on
-    modules (e.g., loading the ``cray-mpich`` module adds MPI libraries to the
-    compiler wrapper link line).
-
-You can set the default compiler that Spack can use for each compiler type.
-If you want to use the Cray defaults, then set them under ``all:`` in packages.yaml.
-In the compiler field, set the compiler specs in your order of preference.
-Whenever you build with that compiler type, Spack will concretize to that version.
-
-Here is an example of a full packages.yaml used at NERSC
-
-.. code-block:: yaml
-
-   packages:
-     mpich:
-       externals:
-       - spec: "mpich@7.3.1%gcc@5.2.0 arch=cray_xc-CNL10-ivybridge"
-         modules:
-         - cray-mpich
-       - spec: "mpich@7.3.1%intel@16.0.0.109 arch=cray_xc-SuSE11-ivybridge"
-         modules:
-         - cray-mpich
-       buildable: False
-     netcdf:
-       externals:
-       - spec: "netcdf@4.3.3.1%gcc@5.2.0 arch=cray_xc-CNL10-ivybridge"
-         modules:
-         - cray-netcdf
-       - spec: "netcdf@4.3.3.1%intel@16.0.0.109 arch=cray_xc-CNL10-ivybridge"
-         modules:
-         - cray-netcdf
-       buildable: False
-     hdf5:
-       externals:
-       - spec: "hdf5@1.8.14%gcc@5.2.0 arch=cray_xc-CNL10-ivybridge"
-         modules:
-         - cray-hdf5
-       - spec: "hdf5@1.8.14%intel@16.0.0.109 arch=cray_xc-CNL10-ivybridge"
-         modules:
-         - cray-hdf5
-       buildable: False
-     all:
-       compiler: [gcc@5.2.0, intel@16.0.0.109]
-       providers:
-         mpi: [mpich]
-
-Here we tell spack that whenever we want to build with gcc use version 5.2.0 or
-if we want to build with intel compilers, use version 16.0.0.109. We add a spec
-for each compiler type for each cray modules. This ensures that for each
-compiler on our system we can use that external module.
-
-For more on external packages check out the section :ref:`sec-external-packages`.
