VLCHTTPUploaderController: Move supported playlist at timeout

Move supported playlists files to the medialibrary discoverable path at the end of a 4sec timer.

Indeed, in the case where the playlist was downloaded first, it could lead to having ghost playlists since the medialibrary parsed the playlist with yet nonexistent media files.
