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
