Add -L and -U options to eject(1) that call DIOCLOCK. Also generally clean

stuff up, correct the usage message and update the manpage to match.

Note that the new options aren't wonderfully useful, since cd(4) at least
promptly unlocks the drawer when eject closes the device.

Most disk drivers automatically lock the media on the first open and
unlock it on the last close, making

again.
