    oxnas: now longer build KD20 factory image
    
    The image never worked in any release and is also broken in snapshots
    due to stock bootloader not loading more than 4 MiB.
    Hence it's better to remove the image for now, users who want to flash
    OpenWrt on new devices may build LEDE 17.01 with everything possible
    disabled to get a small enough and working factory image.
