Omar Ramadan c41817fcaf selftests: net: amt: check that the relay's queries bypass the amt device
The relay used to hand its General Queries to dev_queue_xmit() on the
amt device, where a query could wait in a qdisc and outlive the tunnel
it pointed to. The previous patch sends them directly from the receive
path instead.

Count the IGMP and MLD queries that leave the relay through amtr with
tc flower filters on its egress, installed before the gateway comes
up, and check that there are none. The forwarding tests before it
already show that the gateway received its queries, since it cannot
join without one.

Without the previous patch the new test fails (one run counted 7 IGMP
and 6 MLD queries); with it, all of amt.sh passes.
