perf tools: Allow all_cpus to be a superset of user_requested_cpus

Browse Source 
To support collection of system-wide events with user requested CPUs,
all_cpus must be a superset of user_requested_cpus.

In order to support all_cpus to be a superset of user_requested_cpus,
all_cpus must be used instead of user_requested_cpus when dealing with CPUs
of all events instead of CPUs of requested events.
