SPARK-4147 [CORE] Reduce log4j dependency Defer use of log4j class until it's known that log4j 1.2 is being used. This may avoid dealing with log4j dependencies for callers that reroute slf4j to another logging framework. The only change is to push one half of the check in the original `if` condition inside. This is a trivial change, may or may not actually solve a problem, but I think it's all that makes sense to do for SPARK-4147.
