Fix signal delivery to remote process; As described in rcmd(3), a signal
is delivered to the remote process via the secondary channel.  So,
the backend driver, rcmd(1), is responsible to watch the file descriptor 2
and transfer the data to the remote process, rather than receiving signal
by itself.  Previously, signal generated by tty was sent since rcmd was
incorrectly generated the data, but, for example, signal sent to rsh command
by kill command was ignored.
