Teach AbstractBestPathSelector about depreferenced routes

draft-uttaro-idr-bgp-persistence-04 mandates that routes tagged
with LLGR_STALE are to be used as routes of least preference.

Teach best path selection about this use it as the first step
of discrimination: depreferenced paths will always lose to
non-depreferenced paths.
