socket: Allow disabling multicast loop on socket creation

This introduces a new flag OSMO_SOCK_F_NO_MCAST_LOOP, which can be used
to disable the looping back of multicast packets transmitted throug this
socket to other local sockets on the machine.

As this looping-back is active by default, a single option to deviate
from the default is deemed sufficient.
