recipes: Fix ALLOW_EMPTY with no package specified

There are various usages of ALLOW_EMPTY with no packages specified. This
is not recommended syntax, nor is it likely to be supported in the future.
This patch improves the references in OE-Core, either removing them if they're
pointless (e.g. when PACKAGES="") or specifying which package it applies to.

(From OE-Core rev: fe81bd4f600877e63433184cfc2e22c33bb77db6)
