In handling the DeletePrinterDriverEx request spoolss needs to issue IO
to the print$ share, to do so it creates a fake connection struct.
This change-set fails in share_access_check() when checking the print$
share DACL (grant full access to global_sid_World) against the system
token, as the system token does not include global_sid_World.
Adding global_sid_World to the system security token allows the test to
pass, however this should not be necessary.
DeletePrinterDriverEx should be handled by the RPC server as the user
connected to the spoolss pipe (unless force user/group is set), the
system security token should be irrelevant through this code path IIUC.
