Subject[PATCH 47/73] perf tools: Use perf_mmap way to detect aux mmap
Date
We will move this code into libperf shortly, so we
need to free it of 'struct auxtrace_mmap' usage,
because it won't be available in libperf (for now).

The perf_event_mmap_page::aux_size is set when the
aux mmap is mapped, so the check is equivalent.
