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.
