Subject: [PATCH 3/3] perf bench: Fix sched-message.c for more confortable output

This patch fixes sched-message.c for more confortable output.
Change points are comment style description and
formatting numerical values and its units.

Example of use:
| % 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]
