These were added by
8bf4bec (add "ok=sigpipe" to
test_must_fail and use it to fix flaky tests, 2015-11-27)
because we would racily die via SIGPIPE when the pack was
rejected by the other side.
But since we have recently de-flaked send-pack, we should be
able to tighten up these tests (including re-adding the
expected output checks).
