Replace use bpf_get_ns_current_pid_tgid, as it only matches in the exact same namespace and not child namespaces. This iterates up to 4 namespace levels up to find a match.

If the ebpf profiler is running on another namespace than the host PID namespace, then the PIDs that are selected by Grafana Agent are not matching up with the ones collected.
This will respect the PID namespace the original process is running under.
