Pull ktest update from Steven Rostedt:

 - Fix failure of directory of log file not existing

   If a LOG_FILE option is set for ktest to log its messages, and the
   directory path does not exist. Then ktest fails. Have ktest attempt
   to create the directory where the log file exists and if that
   succeeds continue on testing.
