perf evlist: Store 'overwrite' in struct perf_mmap
It has been determined that the map is for overwrite mode
(evlist->overwrite_mmap) or non-overwrite mode (evlist->mmap) when
calling perf_evlist__alloc_mmap().
Store the information in struct perf_mmap, which will be used later to
simplify the perf_mmap__read*() interfaces.
