zebra: Start carrying safi for rnh processing

PIM is going to need to be able to send down the address it is
trying to resolve in the multicast rib.  We need a way to signal
this to the end developer.  Start the conversion by adding the
ability to have a safi.  But only allow SAFI_UNICAST at the moment.
