Do not use depfile in bootstrap (#41458)

- we don't have a fallback if make is not installed
- we assume file system locking works
- we don't verify that make is gnu make (bootstrapping fails on FreeBSD as a result)
- there are some weird race conditions in writing spack.yaml on concurrent spack install
- the view is updated after every package install instead of post environment install.
