hook: ensure stderr is flushed when an exception is raised, for test stability
Windows has had issues with output order in test-ssh-proto-unbundle.t[1] since
it was created a few weeks ago. Each of the problems occurred when an exception
was thrown out of the hook.
Now the only thing blocking D2720 is the fact that the "abort: ..." lines on
stderr are totally AWOL. I have no idea where there are.
