Add an 'unwanted packages' test, run on Workstation for now (#218)

This adds a test that just fails if any one of a given list of
unwanted packages is installed. This was a request for the
Workstation edition from @catanzaro so I've just implemented it
for Workstation so far, but it's designed to be easily extended
to cover other subvariants too if we want.
