udp: Don't drop zero-length outbound UDP packets
udp_tap_handler() currently skips outbound packets if they have a payload
length of zero. This is not correct, since in a datagram protocol zero
length packets still have meaning.
Adjust this to correctly forward the zero-length packets by using a msghdr
with msg_iovlen == 0.
