When running bpftrace programs against a pod, only show the specific pod processes

[fntlnz]

Right now when you run a bpftrace program against a pod, that is only using the pod to determine the actual binary to use to export symbols by giving you the $container_pid variable.

A better pod support would involve having the possibility to filter only pod tasks so that the results are only relevant to the specific pod.
