Subject: Nest: Fix leaking internal attributes in RIP and Babel

During backporting attribute changes from 3.0-branch, some internal
attributes (RIP iface and Babel seqno) leaked to 'show route all' output.
Allow protocols to hide specific attributes with GA_HIDDEN value.

Thanks to Nigel Kukard for the bugreport.
