tools: xencommons NetBSD init script: Multiple bugfixes and improvements

Added a cleanup of the xenstore database, to purge old entries,
prevented the restart of xenstore and set Domain-0 name.  Also
replaced the sleep 5 (wait for xenstore to come up) with the method
used in the linux init script.
