When creating a new schema for a non-relocatable extension, we neglected to check whether the calling user has permission to create schemas. That didn't matter in the original coding, since we had already checked superuserness, but in the new dispensation where users need not be superusers, we should check it. Use CreateSchemaCommand() rather than calling NamespaceCreate() directly, so that we also enforce the rules about reserved schema names. Per complaint from KaiGai Kohei, though this isn't the same as his patch.
