Subject: Add more caching to the CI

more specificaly to the tarballs download. The function CT_Fetch now
touches the already existing files to be comparable to the not used ones
that can araise when a package is updated.
This comparsion is needed because if it would not exist the tarball
would grow in size due to not used but still cached packages.
This would take time but is definitly something to worry about.
