in_mcat.c: change multicast not member condition
If there is no source filter entry => block if that's SSM ("exclude"
mode per RFC 3678 clause 3). If there is an entry => check its action &
block if the action is "exclude".
It would be nice if the test case in this PR were converted into an ATF
test case, but not blocking on that.
