selftests: router_bridge_vlan_upper_pvid: Add a new selftest
This tests whether changes to PVID that coincide with an existing VLAN upper throw off forwarding. This selftests is specifically geared towards offloading drivers, but since there's nothing HW-specific in the test itself (it absolutely is supposed to pass on SW datapath), it is put into the generic forwarding directory.
