Support tracing of processes under cgroup path

- Using bpf_current_task_under_cgroup() we can check whether the probe
  is being run in the context of a given subset of the cgroup2 hierarchy.
- Support cgroup path '-c' args to get the cgroup2 path
  and filter based on the cgroup2 path fd using bpf_current_task_under_cgroup()
