bpftool: Add support for cgroup_task

laoar · Kernel Patches Daemon · commit 63b3a9c0bce0 · 2023-07-16T05:17:57.000-07:00
we need to make corresponding changes to the bpftool to support
cgroup_task iter.

The result:
$ bpftool link show
3: iter  prog 15  target_name cgroup_task  cgroup_id 7427  order self_only
