README: don't say it's possible to use loopback, it's not #87

Closed vincentbernat closed 7 years ago

In b81bbd, it was added that using loopback should be possible if multicast flag was added. However, in config.c, IFF_LOOPBACK flag on an interface makes it impossible to use a loopback interface.

In fact, I would be very interested to use the loopback. I would like to send local traffic to a multicast address but I have multiple output interfaces. I'd like to be able to bind to loopback and let pimd advertises the multicast endpoint. So I'll try to remove the limitation in config.c instead.

Well, this works just fine let me do another PR instead.

Good catch, must've been from when I was about to remove that limitation myself but never really got around to it.
