perf stat: Allocate evsel->stats->aggr properly
The perf_stat_config.aggr_map should have a correct size of the
aggregation map. Use it to allocate aggr_counts.
Also AGGR_NONE with per-core events can be tricky because it doesn't
aggreate basically but it needs to do so for per-core events only.
So only per-core evsels will have stats->aggr data.
Note that other caller of evlist__alloc_stat() might not have
stat_config or aggr_map.
