kbuild: handle compressed cpio initramfs-es
Make kbuild handle compressed cpio initramfs-es. An already compressed
cpio is copied directly to usr/, while a non-compressed cpio is filtered
through gzip (no changes here) on its way to usr/.
If the user has created a compressed cpio by other means, this saves him
from uncompressing it, just to be compressed again by kbuild.
