    flatpak: Add tracker-miners
    
    This is required for:
      - The org.freedesktop.Tracker.Miner.Files:index-recursive-directories
        setting for custom locations added through Settings -> Search
      - Reading the status of the filesystem miner using
        tracker_miner_manager_get_status.
    
    Note that the latter works through the
    /share/tracker/miners/org.freedesktop.Tracker1.Miner.Files.service
    file, which is a symlink to the filesystem miner's D-Bus service file.
    A working symlink is necessary for tracker_miner_manager_get_status to
    work. Otherwise, it leads to this on startup:
      Tracker-WARNING **: Error parsing miner .desktop file: No such file
        or directory
