net: bridge: BROPT_FDB_LOCAL_VLAN_0: Look up FDB on VLAN 0 on miss

When BROPT_FDB_LOCAL_VLAN_0 is enabled, the local FDB entries for the
member ports as well as the bridge itself should not be created per-VLAN,
but instead only on VLAN 0.

That means that br_handle_frame_finish() needs to make two lookups: the
primary lookup on an appropriate VLAN, and when that misses, a lookup on
VLAN 0.

Have the second lookup only accept local MAC addresses. Turning this into a
generic second-lookup feature is not the goal.
