buildcache: do one less tar file extraction

The buildcache is now extracted in a temporary folder within the current store,
moved to its final place and relocated. 

"spack clean -s" has been extended to also clean the temporary extraction directory.

Add hardlinks with absolute paths for libraries in the corge, garply and quux packages
to detect incorrect handling of hardlinks in tests.
