Add GitHub workflows for extra coverage

This adds a workflow for building Unit under Fedora Rawhide.

Rawhide is the development distribution for Fedora from which releases
are cut.

This usually consists of the latest versions of software and will
hopefully catch new compiler issues and API breakages in the various
languages we support.
