selftests: net: bridge: add vlan mcast querier test 



Add a test to try the new global vlan mcast_querier control and also
verify that tagged general query packets are properly generated when
querier is enabled for a single vlan.

TEST: Vlan mcast_querier global option default value                [ OK ]
TEST: Vlan 10 multicast querier enable                              [ OK ]
TEST: Vlan 10 tagged IGMPv2 general query sent                      [ OK ]
TEST: Vlan 10 tagged MLD general query sent                         [ OK ]
