http: fix missing 'Content-Length: 0' while negotiating auth

- While negotiating auth during PUT/POST if a user-specified
  Content-Length header is set send 'Content-Length: 0'.

This is what we do already in HTTPREQ_POST_FORM and what we did in the
HTTPREQ_POST case (regression since afd288b).

Prior to this change no Content-Length header would be sent in such a
case.
