[SPARK-21728][core] Follow up: fix user config, auth in SparkSubmit logging.
- SecurityManager complains when auth is enabled but no secret is defined;
SparkSubmit doesn't use the auth functionality of the SecurityManager,
so use a dummy secret to work around the exception.
- Only reset the log4j configuration when Spark was the one initializing
it, otherwise user-defined log configuration may be lost.
Tested with the log config file posted to the bug.
