Provide puppet-agent on RPM

This allows users to perform `dnf install puppet-agent` and get
openvox-agent instead. It also means packages don't need to modify their
dependencies. They probably still should, but this helps users migrate.

It also tightens the Obsoletes statement to include a version. rpmlint
raises the unversioned-explicit-obsoletes warning on the old case. The
Conflicts is kept unversioned, which is correct.
