pacsort: add -f, --files option for sorting filenames

Teach pacsort to understand package filenames and optionally strip away
some of the context. alpm_pkg_vercmp() intentionally only understands
pure versions, so strings such as '18.0-2-x86_64' and '18.0.1-1-x86_64'
will be compared wrongly.

Partially addresses FS#33455.
