netinet: do route lookup when asked to join multicast group on ifindex 0

The code to do the route lookup was already there, but was used only for
the legacy IP_ADD_MEMBERSHIP when called without index. Do same lookup
for IP_ADD_MEMBERSHIP with index and what is more important for
MCAST_JOIN_GROUP, if the supplied index is 0. This is a neat feature and
Linux does that, so this should make a few applications easier portable to
FreeBSD.

tests/multicast: fix test flakyness

The receiver is run as a background job, so we need a wait loop to
make sure it has been fully functional before launching sender.

tests/netinet: extend IPv4 multicast testing framework

Provide a helper program multicast-receive.c that joins arbitrary group on
arbitrary specified interface and receives a single datagram and prints it
out.

In multicast.sh provide a template with two jails connected by two
interface pairs, so that we can check sends/receives in presence of
multiple interfaces.

Compose a few basic tests to check legacy and new IP_ADD_MEMBERSHIP and
MCAST_JOIN_GROUP.
