fixes getting the target PID in the oomkill example by using BPF_CORE_READ(oc, chosen, tgid) instead of getting the current pid
enables exposing the events as metrics by default, so people can just pull/use the upstream image. The cardinality of the labels in this case is low, so I think this is a sensible default.
