These headers are needed for defining kernel probes etc, tested with
eBPF. Could also be used for perf, building kernel modules etc. Saved

Also rationalise the paths in the headers tarball a little to match.
Will add an eBPF container using these later.

Add toybox statically linked ls, sh, find etc so that it is
