set proper PACKAGE information for yams 0.39
Yams 0.39 adds an unobstrusive API to get the package, or cube, defining a part
of the schema (entity type, relation type/def).
As CubicWeb overrides part of the schema reading process, we have to handle this
information on our side so it will be properly set.
