Don't remove unknown files in cache cleaning code

This removes the hack I added to skip '*.sig' files earlier since there
are other files that also fall into the same bucket- source packages
from `makepkg --source`, delta files, etc. Rather than prompting for
each and every one, simply skip them. Doing '-Scc' rather than '-Sc'
will delete these files if that is really what you want to do.
