perf stat: Use thread map index for shadow stat
When AGGR_THREAD is active, it aggregates the values for each thread.
Previously it used cpu map index which is invalid for AGGR_THREAD so
it had to use separate runtime stats with index 0.
But it can just use the rt_stat with thread_map_index. Rename the
first_shadow_map_idx() and make it return the thread index.
