Scgi: removed error if there is no Status header.

The SCGI specification doesn't specify format of the response, and assuming
CGI specs should be used there is no reason to complain.  RFC 3875
explicitly states that "A Status header field is optional, and status
200 'OK' is assumed if it is omitted".
