perf stat: Create the runtime_stat init/exit function
It mainly initializes and releases the rblist which is defined in struct
runtime_stat.
For the original rblist 'runtime_saved_values', it's still kept there
for keeping the patch bisectable.
The rblist 'runtime_saved_values' will be removed in later patch at
switching time.

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