pflocal: fix port leak when receiving port rights

The socket_send and socket_recv routines can be used to transmit port
rights along data. Unfortunately, pflocal retains a copy of these rights
in the socket_recv RPC. These lingering references would in turn lead to
other leaks in servers waiting for a no-sender notification to clean
their resources. Since these copied rights aren't used at all by the
server, it is safe to simply move them to the recipient instead.

* pflocal/socket.c (S_socket_recv): Transmit port rights using
MACH_MSG_TYPE_MOVE_SEND transfer type instead of MACH_MSG_TYPE_COPY_SEND.
