            Log:
            add the cups-lpd test to upstream repo

The cups-lpd package is available in various versions of RHEL
and Fedora. The cups-lpd service is also used in these
environments, so it makes sense to run this TC in upstream
testing too.
Moving the downstream TC to upstream repository.
There are only slight changes when comparing the upstream and
downstream version of this TC.
