MDL-73588 curl: Fix expected CURLOPT_FILE behavior

Browse Source 
After cbf9dfb the CURLOPT_FILE no longer behaves as expected. All
redirect responses are appended to the same stream resource.  This fix
reverts back to the old behavior by setting the stream pointer back to
the beginning for each subsequent redirect.
