releasing serial ports after killing cu

[Alexis Rosen]

cu (and all the other programs that respect uucp's locking protocol) creates
lock files in /usr/spool/uucp. If it grabs tty1, it will make a file called
LCK..tty1 and place in it its process ID.

Unfortunately, cu is broken, as are some (all) of the other programs. They are
supposed to check for (and remove) stale locks, but they don't.
