perf evsel: Add 'no_aux_samples' option
Add an option to prevent additional samples being added to a selected
event by perf_evsel__config().
This is needed when using the sched_switch tracepoint to follow object
code execution. Since sched_switch will be used only for switch
information, additional sampling is wasteful.
