rtsp: gstrtspurl: gst_rtsp_url_get_request_uri: use rtsps scheme for tls transport...

gst_rtsp_url_get_request_uri returns rtsp://... url when requested url is rtsps://, this is not
in accordance with https://www.rfc-editor.org/rfc/rfc7826.html#section-19.2.
This also impedes setting up a rtsps session with a live555 rtsp server.

Don't expose other than rtsp and rtsps internal gstreamer rtsp url schemes
to avoid regression:
