efl_net_dialer_http: allow incompatible configurations such as GET + upload.

CURL is smart and when you ask for CURLOPT_HTTPGET, it will
automatically configure UPLOAD=false. Likewise, if you ask for
UPLOAD=1 it will configure CURLOPT_PUT...

However, to do things like WebSocket we need to do a GET request where
we need to send data, then UPLOAD=true must be used.

Then use both information in order to setup the request method and
upload, using CURLOPT_CUSTOMREQUEST to force a given HTTP method.
