Solve segfaults from unusual error exceptions in cgid. The daemon

  has no 'real' request_rec, so we can't use ap_log_rerror() anywhere
  within the cgid_server() code.

  Also, one of the two log messages was echoed to the child, no point
  when the actual request logic should take care of that notification.
