Title: if release notes package was updated, show release notes at the … end (fate#314072)

This is simpler solution, proper way would be to adapt pkg-bindings so it can return packages that are part of selected patch.

But this is imho good enough for SP3 (keep changes local). For factory, we might want to implement something better.
