    gamepad-view: Fix gamepad svg loading with old librsvg
    
    For some reason loading with 'new Rsvg.Handle.from_file()' fails, while
    loading gresource manually and creating handle via 'from_data()' works, so
    let's go with that.
    
    Also remove 'resource:' prefix from paths, since they aren't needed
    anymore.
