Add files attribute to RpmUnit [RHELDST-21555]

This commit adds an attribute, files, to RpmUnit which maps to the
'files.file' pulp field and holds a list of files provided by the RPM.

The immediate use case for this is in ubi-manifest to identify available
files which may match those listed as dependencies, avoiding unnecessary
pulp searches.
