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.
