makedevs: add nativesdk to BBCLASSEXTEND

This is a first in a series of patches to add items
to the nativesdk toolchain tarball.
Many of which are Yocto specific and needed to create a
rootfs with pre and post install hooks successfully run,
using only the toolchain tarball.

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