[PATCH 0/3] Fixups for git-maintenance(1) tests

Hi,

this small patch series fixes up the test flakes and issues on Windows as reported by Peff:

  - We now wait for git-maintenance(1) to run to completion.

  - Instead of checking for the detach logic via the output, we now have
    a new trace2 region that allows us to check whether the detaching
    logic was executed.

  - Fix another bug that caused the "loose-objects" task to emit the
    packfile hash. This is a preexisting issue, but Peff made me have a
    deeper look at it.
