perf stat: Allocate shadow stats buffer for threads
After perf_evlist__create_maps() being executed, we can get all threads
from /proc. And via thread_map__nr(), we can also get the number of
threads.
With the number of threads, the patch allocates a buffer which will
record the shadow stats for these threads.
The buffer pointer is saved in stat_config.
