libperf: Introduce perf_evlist_mmap_ops::mmap callback
Add the perf_evlist_mmap_ops::mmap callback to be called in
mmap_per_evsel() to actually mmap the map.
Add libperf's perf_evlist__mmap_cb_mmap() function as libperf's mmap
callback.
New mmaped map gets refcount set to 2 in mmap__mmap(), we follow that in
mmap callback. We will move this to common place after we switch to
perf_evlist__mmap().
