Subject: gnu: Add java-eclipse-rdf4j-model-api.

Since RDF4J is a large framework with many parts, this patch also prepares
some boilerplate code for the other packages.

* gnu/packages/java-rdf.scm (%rdf4j-version, %rdf4j-sha256, %rdf4j-source)
(rdf4j-common-arguments): New variables.
(java-eclipse-rdf4j-model-api): New variable.
