gstreamer: Change SRC_URI to use HTTPS access instead of HTTP
Some GStreamer recipes like gstreamer1.0-vaapi already use HTTPS instead
of http. Also, access to http:// is simply redirected by the freedesktop
server to https://, and using HTTPS is anyway generally recommended over
plain HTTP for security reasons. So, normalize the URLs to use HTTPS only.
