debian.bbclass: inherit package

debian.bbclass: inherit package

This class defines a package_name_hook implementation but as EXPORT_FUNCTIONS is
order-dependent it needs to inherit package.bbclass first to ensure that the
"base" definition in there is defined first, otherwise with a suitable inherit
order of debian and then a packaging class can result in the stub
package_name_hook being incorrectly used.
