cmd/mkinitfs: don't compress initramfs-extra (MR 25)

Browse Source 
There is little(?) reason to compress the -extra archive, but some
there are some good reasons why it should be left uncompressed:

        1) decompression increases boot time
        2) selecting exotic formats (e.g. lzma or zstd) can actually
           increase the initramfs size since you now have to include
           support for those archive formats

In the future this could be made configurable...
