Add referer to remote media requests. (#8135)

Browse Source 
This sends the following header to a remote media server:

    Referer: minetest://<server_name>:port

This was verified with CTF and the Minetest Public Remove Media
server. If the servername was a plain IPv6 address it will
contain `:` characters and will be encapsulated in `[]` to
be a valid URI.
