    Add zstd compression support · 830b8ddc

    Now that 5.10 is out and supports zstd compression for the kernel and
    initramfs, add support for zstd to mkinitfs. The benefits have been
    discussed at length on lkml[1][2].
    In my personal experience, the compression (mkinitfs) seems to be
    slower, but decompression (booting) seems to be faster. I think most
    people boot more than they mkinitfs.
    The default is still gzip, so no change should be noticed unless
    someone goes looking for trouble.
    To test this functionality, just add the following to mkinitfs.conf:
