[SPARK-17276][CORE][TEST] Stop env params output on Jenkins job page

https://issues.apache.org/jira/browse/SPARK-17276

## What changes were proposed in this pull request?

When trying to find error msg in a failed Jenkins build job, I'm annoyed by the huge env output.
The env parameter output should be muted.
