pkg-generic: introduce helper function to check for a deprecated variable 



This patch introduces a helper check-deprecated-variable, that throws an
error when a package defines a deprecated variable. This helps in detecting
transition errors when changing the buildroot infrastructures, and also
helps users that have created packages not part of mainline buildroot.
