[FIX] Usability bug fix in server_ctt

- At present the check "help" in argv to call the
   usage() function is not handled as expected
 - In either case the the code goes into the if
   condition and returns EXIT_SUCCESS
 - Fix the minor issue so that code returns this status
   if it identifies --help or -h
