[src/trunk]: src Run mcast tests on rump kernels
details: https://anonhg.NetBSD.org/src/rev/07b025e4d9f3
branches: trunk

description:
Run mcast tests on rump kernels
The tests on anita qemus failed due to that the host network environment
didn't meet the tests.
The change makes the tests independent from host environments
and the tests will pass on any environments including anita qemus.
Discussed on tech-kern and tech-net.
