perf stat: Update per-thread shadow stats
The functions perf_stat__update_shadow_stats() is called to update the
shadow stats on a set of static variables.
But the static variables are the limitations to be extended to support
per-thread shadow stats.
This patch lets the perf_stat__update_shadow_stats() support to update
the shadow stats on a input parameter 'st' and uses
update_runtime_stat() to update the stats. It will not directly update
the static variables as before.

[ Rename 'stat' variables to 'st' to build on centos:{5,6} and others where it shadows a global declaration ]
