Various updates
    
    - Drop the old sysv init script
    - Fix opensm-launch to restart opensm in a loop.  This works around the
      fact that systemd starts opensm so early that we very well might not
      have sync on the link yet.  Without the physical link being up, opensm
      exits immediately.  This way opensm will get restarted every 30 seconds
      until sync is active on the link or until the opensm service is
      stopped.
    - Always install the newly generated opensm-%%{version}.conf as
      opensm.conf
    - Make the launch work properly in the event that no GUIDs are
      set and there are no numbered config files
