cp2k is now a MakefilePackage (#10570)

* cp2k: archive the Makefile after a successful installation

* cp2k: all checksums are now sha256

* libint: all checksums are now sha256 + added versions 2.4.X

* libxc: all checksums are now sha256 + added version 4.3.2

* cp2k: os.path.join instead of join_path + simplified openmp flags

* cp2k: turned into a MakefilePackage

* cp2k: refactored edit method so that Makefile writing happens last
