perf bench: Improve sched-message.c with more comfortable output
This patch improves sched-message.c with more comfortable output.
Change points are comment style description and
formatting numerical values and its units.
Example:
| % perf bench sched messaging
| # Running sched/messaging benchmark...
| # 20 sender and receiver processes per group
| # 10 groups == 400 processes run
|
| Total time: 1.490 [sec]
