checkpkg: Simulating a catalog with installed pkgs

When examining a set of packages, replace file information from the catalog
with information from packages under test.

Also, satisfy a group dependency (CSWfoo1 or CSWfoo2 or CSWfoo3...) if one of
the alternative packages needed is the package under examination.
