Merge branch 'bpf-libbpf-add-types'

Andrey Ignatov says:

====================
v1->v2:
- add new types to bpftool-cgroup man page;
- add new types to bash completion for bpftool;
- don't add types that should not be in bpftool cgroup.

Add support for various BPF prog types and attach types that have been
added to kernel recently but not to bpftool or libbpf yet.
====================
