patch to not create the /vservers/slicename/vsys directory until vuseradd has

created /vservers/slicename, then report the difference so that vsys can be
restarted even if the configuration files have not been movidifed.

Restarting vsys will ensure that it re-reads the config file.  The preferred
long-term solution is for vsys to auto-read it's config files using the
same/similar inotify mechanism used on the pipes.
