ebpf profiling does not work in kind

[korniltsev]

-pid=host does not work in kind and it runs in a separate pid namespace

https://github.com/kubernetes-sigs/kind/issues/3182

If the pods are running as privileged(I am not 100% sure) we may consider adding an option to try to escape the pid namespace with https://blog.trailofbits.com/2019/07/19/understanding-docker-container-escapes/ for smoother dev experience

we should improve and autodetect if not running root pid namespace

We now compare the PID in ebpf with the same PID namespace that is used in userspace
