    image: fix ar71xx legacy images
    
    If TARGET_PER_DEVICE_ROOTFS and DEVICE_PACKAGES are used for ar71xx
    legacy images:
    
    - an already jffs2 padded squashfs rootfs is overwritten
      with an unpadded/raw one.
    
    - the squashfs-raw and squashfs-64k rootfs are not replaced by the
      ones including the DEVICE_PACKAGES
    
    Call Image/Build/squashfs after the DEVICE_PACKAGES are added to the
    base squashfs rootfs to fix the issues.
    
    Fixes: FS#904
