test: case: static_multicast_filters: Speed up positive reception tests

Browse Source 
Use must{,_not}_receive instead of the general sniffer, so that we can
continue the test as soon as we see the transmission at the receiver,
rather than always waiting the full 5s.

While we're here:
- Show the port mappings in the top block-comment
- Define a few more steps to show the user what is going on
- Avoid global variable references in set_static_multicast_filter()
