Public bug reported:
[Impact]
Upgrades to noble chmod /dev/null 644, breaking use of the device on multi-user
systems for non-root.
[Test plan]
1. do-release-upgrade mantic -> noble
2. check that /dev/null remains 666
[Where problems could occur]
[Details]
This is a regression of the fix for bug 2064090, where we pointed
apt_pkg.config["Dir::State::extended_states"] = "/dev/null" in the simulation
to not lose the automatically installed bit, as we need that later, apt chmod's
it extended_states.
The fix for this is to create a temporary file for extended_states, and
then remove the temporary file at the end of the simulation.
