The default filterref is still clean-traffic, but we can now set it to
"no-broadcast-mac" for the test by that same name.
This corrects a problem with the no-mac-broadcast test, which was
checking to see that packets with a destination MAC address of
ff:ff:ff:ff:ff:ff weren't allowed, but was neglecting to add the
"no-mac-broadcast" nwfilter to the domain (the test was erroneously
succeeding because it was checking for a different type of packet than
it was generating, which is fixed in a separate patch).
