perf stat: Print per-thread shadow stats

Browse source 
The function perf_stat__print_shadow_stats() is called to print the
shadow stats on a set of static variables.

But the static variables are the limitations to support
per-thread shadow stats.

This patch lets the perf_stat__print_shadow_stats() support
to print the shadow stats from a input parameter 'st'.

It will not directly get value from static variable. Instead,
it now uses runtime_stat_avg() and runtime_stat_n() to get and
compute the values.

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