Back when the distribution launchers were compiled to target JDK 7, we did not have access to the String#join method to space-delimit JVM options. Since the launchers now target the same minimum JDK as Elasticsearch itself, we now have access to this method and can replace the use of spaceDelimitJvmOptions with String#join. This commit does that.
