Extend the docker and IOU relay negative controls with the filters the
relay itself supports (delay, frequency_drop, bpf), asserted through real
ICMP — the first live coverage of the relay filter path:
* bridge engine (docker): delay 100 grows the RTT by ~200 ms and comes
back on clear; frequency_drop 2 kills the round trips (the filter counts
every packet crossing the bridge, both directions sharing one counter,
so on an alternating ping stream one whole direction dies; verified
against uBridge directly), frequency_drop -1 blackholes, and bpf drops
by libpcap expression ('icmp', then 'greater 150' discriminating by
frame size).
* iol_bridge engine (IOU): the same delay and frequency_drop effects
through the port's iol_bridge filter list, plus the available_filters
spot check.
Docker 33 s, IOU 168 s, both green.
