Before defining the package for the generic_service, check if it is
already defined, either by $noval_title or $package_name naming.
Create dependency relationship(s) with the service resource based
on how the package is defined in the catalog.
Otherwise, it's possible to end up with a duplicate package definition,
or, more likely, the dependency from the service definition to break.
This occurs most specifically with the spicehtml5proxy class on
EL-based platforms.
