udp: Pre-populate msg_names with local address
udp_splice_namebuf is now used only for spliced sending, and so it is
only ever populated with the localhost address, either IPv4 or IPv6.
So, replace the awkward initialization in udp_sock_handler_splice()
with statically initialized versions for IPv4 and IPv6. We then just
need to update the port number in udp_sock_handler_splice().
