perf bench: Modify builtin-pipe.c for processing common options
This patch modifies builtin-pipe.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 pipe # with no style specify
(executing 1000000 pipe operations between two tasks)
Total time:5.855 sec
5.855061 usecs/op
170792 ops/sec
% ./perf bench --format=simple sched pipe # specified simple
5.988
