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] Signed-off-by: Hitoshi Mitake <[email protected]> Cc: Peter Zijlstra <[email protected]> Cc: Paul Mackerras <[email protected]> LKML-Reference: <[email protected]> Signed-off-by: Ingo Molnar <[email protected]> Cc: Peter Zijlstra <[email protected]> Cc: Paul Mackerras <[email protected]>
