    align kmod_compress_cmd with current kernel
    
    even though it's unused with MODULE_COMPRESS_XZ=y
    
    kernel's embedded xz decompressor does not support xz's default crc64
    checksum algorithm so it needs to be explicitly set to either crc32 or
    none. otherwise module is not recognized if decompression happens in
    kernel (available since kernel >= 6.4 + kmod >= 31)
