These headers are needed for defining kernel probes etc, tested with eBPF. Could also be used for perf, building kernel modules etc. Saved to the media tarball at present, may add to base image or container. Also rationalise the paths in the headers tarball a little to match. Will add an eBPF container using these later. Signed-off-by: Justin Cormack <justin.cormack@docker.com>
