    gphoto2: Use G_FILESYSTEM_PREVIEW_TYPE_NEVER
    
    PTP/MTP devices can only transfer complete files, which means that
    generating a thumbnail can often take multiple minutes, and any
    other operation is blocked until this is done. In practice this can
    often prevent meaningful use of the device. So change the hint to
    applications, advising them it is a bad idea to generate thumbnails
    for these devices.
