[SPARK-14072][CORE] Show JVM/OS version information when we run a benchmark program
## What changes were proposed in this pull request?
This PR allows us to identify what JVM is used when someone ran a benchmark program. In some cases, a JVM version may affect performance result. Thus, it would be good to show processor information and JVM version information.
