So there needs to be an empty implementation and EXPORT_FUNCTION for
package_package_name_hook so that you don't get "cannot find function
package_name_hook" when you don't have the debian.bbclass enabled.

In cleaning that up I proposed removing the EXPORT_FUNCTION entirely
for the hook, but Richard recalled there being something out there
that did use the ability to chain up into debian.bbclass's
implementation, so I kept it.
