Vladimir said when adding this test:
The bridge driver fares particularly badly [...] mainly because
it does not implement IFF_UNICAST_FLT.
See commit 90b9566aa5cd ("selftests: forwarding: add a test for
local_termination.sh").
We don't want to hide the known gaps, but having a test which
always fails prevents us from catching regressions. Report
the cases we know may fail as XFAIL.

v3:
- use xfail_on_veth correctly as a "prefix" call
- dropping Vladimir's tags since the code is quite different now
v2: https://lore.kernel.org/r/20240509235553.5740-1-k...@kernel.org/
- remove duplicated log_test_xfail
v1: https://lore.kernel.org/all/20240509235553.5740-1-k...@kernel.org/
