Subject: [PATCH V7 05/12] perf tools: Enable evsel__is_aux_event() to work for S390_CPUMSF

evsel__is_aux_event() identifies AUX area tracing selected events.

S390_CPUMSF uses a raw event type (PERF_TYPE_RAW - refer
s390_cpumsf_evsel_is_auxtrace()) not a PMU type value that could be checked
in evsel__is_aux_event(). However it sets needs_auxtrace_mmap (refer
auxtrace_record__init()), so check that first.

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