Subject: [PATCH] ci/eval/compare: ping maintainers of removed packages

This change pings maintainers of actually removed packages, aka where
the package's expression is deleted.

This will not ping maintainers of packages that become invisible,
because a (transitive) dependency of them is marked as insecure or
broken.
