Draft: Pin our package(s) negatively in the non-target suites
When a package is removed in a new version, for example libssl30 is renamed to libssl30t64, libssl30 from testing should no longer be installable when testing openssl from unstable.
By adding a test
Package: openssl
Pin: release *
Pin-Priority: -1
as this will do, we end up marking any old binaries no longer installable to fix this issue and get an accurate view.
