zebra: mark router flag for remote neigh update

Handle Remote Neigh entry state change from Router to Host.

Remote MAC-IP update may not continue EVPN NA Extended community,
Zebra need to accomodate if router_flag change for existing neigh
and install with or without Router Flag (R-bit).

Testing:
Have locally run MAC/IP (neigh entry) with R-bit set,
Checke on remote VTEP 'show bgp evpn route ...mac ip' and
'show evpn arp-cache ...' contians router flag.

Change host to remove R-bit, which locally learnt entry removes
Router flag. This results in remote vtep to remove R-bit from
neigh entry.
