When narrowing down packages using the "Agent bakery packages" agent ruleset,
it may happen that a host is assigned to two different agent packages after baking.
This may happen when you start using the abovementioned rule. On baking, this will result
in a new agent package for the matched hosts. If nothing else happens to the package
that the hosts were assigned to previously, the now-unselected platforms will remain
for the previous package.
As they are explicitly unwanted by setting the rule, these orphaned packages are now cleaned up.
