[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.
