udp: Don't attempt to translate a 0.0.0.0 source address
If an incoming packet has a source address of 0.0.0.0 we translate that to
the gateway address. This doesn't really make sense, because we have no
way to do a reverse translation for reply packets.
Certain UDP protocols do use an unspecified source address in some
circumstances (e.g. DHCP). These generally either require no reply, a
multicast reply, or provide a suitable reply address by other means.
In none of those cases does translating it in passt/pasta make sense. The
best we can really do here is just leave it as is.
