Use the local repository from the Maven build in OSGi/WildFly integration tests

The current configuration doesn't do that, and it leads to failures in some environments (e.g. CI environment with non-standard location for the local repository).

It looks like an upgrade to pax-url 2.5.4 (like in Hibernate Search 5) will be necessary, because the settings we need don't work in pax-url 2.5.2.
