[Bug 1829860] [NEW] APT unlocks in same order as it locks

[Julian Andres Klode]

Public bug reported:

[Impact]
APT releases the locks in the same order it acquires them, rather than reverse order. Given that we have no waiting for locks, this is not _super_ problematic, but it might be wrong: You'd get a lock failure on dpkg's lock, rather than lock-frontend.

[Test case]
...

[Regression potential]
...
