    ath79: add empty squashfs-lzma filesystem
    
    The filesystem is currently created on every build to trick the boot
    loader of some FRITZ! devices into accepting the image. Sadly the
    resulting squashfs-lzma filesystem is not reproducible. To fix this,
    create a squashfs filesystem once and include it into the repository.
    
    Creation happend as shown below
    
        rm -rf empty_dir
        mkdir empty_dir
        ./staging_dir/host/bin/mksquashfs-lzma \
            empty_dir/ empty-squashfs-lzma \
            -noappend -root-owned -be -nopad -b 65536 -fixed-time 0
