[AF_PACKET]: Allow multicast traffic to be caught by ORIGDEV when bonded

The socket option for packet sockets to return the original ifindex instead
of the bonded ifindex will not match multicast traffic.  Since this socket
option is the most useful for layer 2 traffic and multicast traffic, make
the option multicast-aware.
