bgpd: only rescan EVPN tables if self-mac changes

When processing an interface up/create event from zebra, we insert that
interface's MAC address into the self_mac_hash used for dropping EVPN
routes carrying a 'self mac' (RMAC ext-comm or MAC in Type-2 NLRI).
However, we were unconditionally triggering a "rescan" of the EVPN RIB
to ensure we handle routes that match the MAC - even if the MAC already
existed in self_mac_hash (i.e. the change wasn't actionable).
This adds logic to only kick off a "rescan" if the MAC learned from
zebra is not already in the self_mac_hash.
