perf bench: Modify bench/bench-messaging.c to adopt unified output formatting
This patch modifies bench/bench-messaging.c to adopt
unified output formatting: --format option.
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
