Support for informing the testbed of the node rebooting. Implemented

as a script in init.d that gets called when the node goes into
runlevel 6 (reboot.)

(Note, it has to get 'started' earlier, when going into runlevel 3,
because if it has not created a lockfile in /var/lock/subsys,
it will not get called when shutting down.)
