add a cpio implementation to tools directory

cpio utility is a mess in point of portability.
For example NetBSD cpio implementation does not support
userid and groupid changes for the archive. This
feature is required for initramfs filesystem targets.
This cpio is from the Heirloom project.

Fix needed rebuild of tools, when changing targets.
