Use abspath to avoid permission errors(#7241)

Fixes #5189

When working with non-normalized paths containing ".." on some
file systems, Spack was found to encounter a permission error when
writing to the path. This normalizes a path written by the
intel-parallel-studio package and also normalizes all paths
written by the license install hook (for all packages) to avoid
this issue for intel-parallel-studio.
