perf bench: Modify builtin-bench.c for processing common options

Browse Source 
This patch modifies builtin-bench.c for processing common
options. The first option added is "--format".
Users of perf bench will be able to specify output style by
--format.

Usage example:

 % ./perf bench sched messaging		# with no style specify
 (20 sender and receiver processes per group)
 (10 groups == 400 processes run)

         Total time:1.431 sec

 % ./perf bench --format=simple sched messaging # specified
 simple 1.431
