Yang Jihong f33052802e perf evlist: Add perf_evlist__go_system_wide() helper 
commit f6ff1c7604 upstream.

For dummy events that keep tracking, we may need to modify its cpu_maps.

For example, change the cpu_maps to record sideband events for all CPUS.

Add perf_evlist__go_system_wide() helper to support this scenario.
