BPF updates

Couple of misc updates related to BPF. First removes a BPF sample that is long legacy (pre BPF fs times), then we add support for the loader to be able to take care of map in map, and last but not least we dump id and whether prog was jited in tc filter show for cls/act BPF programs.

The set is intended for -master branch _after_ the -net-next branch got merged into -master branch.

Thanks!
