folks: update result pattern with PASSED|FAILED

Update result pattern regex with explicit "PASSED|FAILED" words for folks test cases where it was left to a wildcard. This caused other log messages such as "NOTE: Run..." to be matched as results. It also seemed to make it more likely for log lines to stumble upon each other and cause some message corrpution.
