[OE-core] [PATCH] shadow: Create recipe nativesdk-shadow

[David Nyström]

This is a second in a series of patches to enable
offline rootfs creation from a package repository.

Some postinstall cmds are Yocto specific and needed to create a
rootfs with pre and post install hooks successfully run,
using only the toolchain tarball + a package repo.

End goal is to create a sandbox where _users_ of a Yocto
based distribution can customize a rootfs from a package feed
with their package manager of choice.

With this patch, I can successfully create packagegroup-core-boot
with only the toolchain tarball(OPKG). More fixes for a few postinstall
hooks outside of packagegroup-core-boot will come next.
