    Fix KDC worker process argument parsing
    
    To create worker processes, the KDC shuts down realms, forks off the
    worker processes, then reinitializes realms in each child.
    Reinitializing realms requires making a second pass over the
    command-line arguments.  To do this with getopt, optind must be
    reinitialized to 1 for each pass; otherwise, no options will be seen
    the second time around.
