[MNG-5756] Java home output in mvn -v is misleading

The Java home displayed corresponds to the property 'java.home' which points to the JRE installation running the given Maven instance. It is not the value of $JAVA_HOME which causes confusion. Ref: https://docs.oracle.com/javase/tutorial/essential/environment/sysprop.html This closes #115 and #117.
