Relax conflict checks for externals (#6907)

Browse Source 
This updates the conflict-checking logic to require that the conflict
spec matches exactly and that all fields mentioned in the conflict
spec are present in the concretized spec in order to report a
conflict. This will automatically skip all conflict checks for
dependencies of externals (since externals strip dependencies). This
will not affect non-external packages since all fields and
dependencies are fully specified for such packages.
