units: add systemd-debug-shell.service
If enabled, the service provides a root shell from an early boot. It also
remains active late into shutdown. It is useful for debugging startup and
shutdown problems.
This is the unit referenced in
http://freedesktop.org/wiki/Software/systemd/Debugging#early_debug_shell
