[cleaner] Only skip packaging-based files for the IP parser

[TurboTurtle]

Files primarily containing package information, e.g. installed-rpms or
installed-debs, were previously being skipped by all parsers. In
reality, we only need to skip these for the IP parser due to the fact
that version numbers often generate a match for IP address regexes.

This will also fix a problem where if a system was the build host for
certain packages, the hostname would remain in these files as the
hostname parser was previously not checking these files.

Closes: #2400
Resolves: #2464
