[OE-core] package_name_hook in debian.bbclass

[Burton, Ross]

Hi,

package_name_hook in debian.bbclass is tagged using EXPORT_FUNCTIONS,
so that other classes can "inherit" it and define their own
foo_package_name_hook, calling up to debian_package_name_hook.

This seems unlikely to actually happen, and I was thinking about
removing the EXPORT_FUNCTIONS tag.  Would this break anyone's code?
