selftests: net: bridge: vlan multicast tests

This patch-set adds selftests for the new vlan multicast options that
were recently added. Most of the tests check for default values,
changing options and try to verify that the changes actually take
effect. The last test checks if the dependency between vlan_filtering
and mcast_vlan_snooping holds. The rest are pretty self-explanatory.

TEST: Vlan multicast snooping enable                                [ OK ]
