Subject: [PATCH bpf-next] bpftool: man: Add missing top level docs

The top-level (bpftool.8) man page was missing docs for a few
subcommands and their respective sub-sub-commands.

This commit brings the top level man page up to date. Note that I've
kept the ordering of the subcommands the same as in `bpftool help`.
