Subject: Add owl:imports to ontologies

These are required by OWL tools to use vocabulary from another ontology.
Though we don't use OWL tools in LV2, they are at least useful for sanity
checking the semantic side of things.  These properties are also nice to have
anyway, since they clearly describe the dependencies between specifications.
