[rubygems/rubygems] Improve source gemfile/lockfile equivalence checks

Since we no longer have multiple global sources, each top level dependency is
always pinned to a single source, so it makes little sense to talk about
adding or removing a source. Instead, source changes always mean to
change the source one or more dependencies are pinned to. This logic can
now be much simpler.
