demux/playlist: itml: do not halt parsing on unsupported track

This change makes it so that a track without <key>Location</key> is
simply ignored, instead of it preventing further tracks within the
playlist to be parsed (as we should of course import as many tracks as
we possibly can, even if there are some we simply cannot handle).
