 Noticed while debugging #23133.

 If a server blocks local connections, `WP_Http_Streams` and
 `WP_Http_Fsockopen` return errors for both blocking and non-blocking
 requests:
 {{{
 WP_Http_Streams: Could not open handle for fopen() to ...
 WP_Http_Fsockopen: "110: Connection timed out"
 }}}

 `WP_Http_Curl`, however, just returns an empty response, which makes
 debugging more difficult: [[BR]]

 http.php#L1145

 The actual error message that `curl_error()` returned was "couldn't
 connect to host".
