zebra: evpn mh sync mac install as inactive

EVPN MH ES reduendant VTEPs need to install
sync MAC as notify inactive and generate
ND:Proxy stamped extended community on Type-2
route.

Ticket:#3436621
Issue:3436621

Testing Done:

tor-11 originates type-2 MAC route:

tor-11# bridge -d fdb show | grep 00:65:00:00:00:01
00:65:00:00:00:01 dev hostbond1 vlan 1000 notify master bridge static

tor-12 receives sync MAC route:

Before fix:
----------
tor-12:/# bridge -d fdb show | grep 00:65:00:00:00:01
00:65:00:00:00:01 dev hostbond1 vlan 1000 notify master bridge static

After fix: inactive is set to MAC entry
----------
tor-12:/#bridge -d fdb show | grep 00:65:00:00:00:01
00:65:00:00:00:01 dev hostbond1 vlan 1000 notify inactive master bridge
static

Notice the difference in `inactive` post notify on tor-12
with the fix.
