The first loop quoted above is inside cgroup_bpf_put()
which is called when cgroup is destroyed. At this point
we're detaching and prog_put all attached programs.

introduce BPF_F_ALLOW_MULTI flag that can be used to attach multiple
bpf programs to a cgroup.
The difference between three possible flags for BPF_PROG_ATTACH command:
- NONE(default): No further bpf programs allowed in the subtree.
- BPF_F_ALLOW_OVERRIDE: If a sub-cgroup installs some bpf program
