Bug description:
  [Impact]
  test-pdiff-usage is somewhat flaky, especially on Debian, this makes it less flaky. No end user impact as it's a test-only change.

  [Test plan]
  Running autopkgtest, which runs our extensive integration test suite which includes the changed test.

  [Where problems could occur]
  No end user regression potential on its own, but might slightly change regression potential for future pdiff changes:

  Test approach is slightly different now. It still catches that updates
  fail correctly, but tests more concretely that a transaction was
  aborted rather than that no worker received work (which was not
  guaranteed, the work could be scheduled before it was aborted).
