[rygel] core: Add XBox hacks

[Zeeshan Ali Khattak <zeeshanak src gnome org>]

commit 2f94f36e638acc84cdb5b6aaa87f307027b2ad86
Author: Zeeshan Ali (Khattak) <zeeshanak gnome org>

    core: Add XBox hacks
    
    If the "User-Agent" header in the request contains "XBox", we assume the
    client is Xbox. The hacks are currently simple: we just override the
    mime-type of the item so that XBox likes it better.
