MODE-2143 Changed the default networking stack of ModeShape build to prefer IPv6

Changed the default networking stack to prefer IPv6, except in the `integration/modeshape-jbossas-integration-tests` module that uses Arquillian (which is limited to IPv4 on Windows; see [JBPAPP-9281](https://issues.jboss.org/browse/JBPAPP-9281) for details) to run EAP on IPv4. In that module, we also have to force our tests to use IPv4.
