perf lock: Implement cpu and task filters for BPF
Add -a/--all-cpus and -C/--cpu options for cpu filtering. Also -p/--pid
and --tid options are added for task filtering. The short -t option is
taken for --threads already. Tracking the command line workload is
possible as well.
$ sudo perf lock contention -a -b sleep 1
