perf auxtrace: Add mmap_needed to auxtrace_mmap_params
Add mmap_needed to auxtrace_mmap_params.
Currently an auxtrace mmap is always attempted even if the event is not an
auxtrace event. That works because, when AUX area tracing, there is always
an auxtrace event first for every mmap. Prepare for that not being the
case, which it won't be when sideband tracking events are allowed on
all CPUs even when auxtrace is limited to selected CPUs.
