Minor BPF cleanups and digest

First two patches are minor cleanups, and the third one adds a prog digest. For details, please see individual patches. After this one, I have a set with tracepoint support that makes use of this facility as well.

Thanks!

bpf: remove type arg from __is_valid_{,xdp_}access bpf, cls: consolidate prog deletion path
bpf: add prog_digest and expose it via fdinfo/netlink
