Some comps cleanup

[Kevin Fenzi]

Re: https://bugzilla.redhat.com/show_bug.cgi?id=1284183

I have removed a bunch of packages that have been orphaned/retired from
comps, but there's still more to be done there. 

There's also a number of packages that have changed name that should
get updated. 

Perhaps someone would care to write a checker script here? 

Check each package in comps, make sure it is no
retired/orphaned/missing and of those look for packages that now
provide that name?
