Call the -u UCMD command on exit. The command is called with the

current unit number, and the "new" unit number of -1.  This allows the
script to actually deconfigure the SLIP interface (e.g. by running
"ifconfig delete") which has been impossible previously.

This is most likely a candidate for 2.1, too.
