pseudo-ethernet: T9253: fix anycast-gateway with shared MAC on bridge VLANs

Several anycast-gateway pseudo-ethernets with the same MAC on different
VLANs of one bridge (the usual EVPN layout) failed to commit with
"bridge fdb add ... File exists". The local FDB entry was always installed
without a VLAN, so every interface competed for the same entry. A failing
commit at boot left only one interface configured and dropped the rest of
the config.

The local FDB entry is now bound to the VLAN of the bridge sub-interface
when the bridge is VLAN aware, and it is installed with replace so a
re-commit over an existing entry no longer fails. Two anycast-gateways
with the same MAC on the same source-interface are rejected.
