Give to Maven the list of produced artifacts by modules

While parsing POMs Maven looks for needed artifacts. nuxeo-distribution-tools must indicate to Maven what it will produce.
An example of the issue is nuxeo-distribution-windows which need nuxeo-distribution-jboss artifacts. When building from nuxeo-distribution, even if nuxeo-disitribution-jboss is in the build lifecycle, while parsing nuxeo-distribution-windows Maven will try to download required artifacts before building the nuxeo-distribution-jboss module.
