    fadump: use 'zstd' as the default compression method

    If available, use 'zstd' compression method to optimize the size of
    the initrd built with fadump support. Also, 'squash+zstd' is not
    preferred because more disk space is consumed with 'squash+zstd' due
    to the additional binaries needed for fadump with squash case.
