Subject: [PATCH V4 03/11] perf tools: Enable evsel__is_aux_event() to work for ARM/ARM64

Set pmu->auxtrace on ARM/ARM64 AUX area PMUs. evsel__is_aux_event() needs
the setting to identify AUX area tracing selected events.

Currently, the features that use evsel__is_aux_event() are used only by
Intel PT, but that may change in the future.
