T3171 doesn't terminate with Interrupted message on Darwin
I am seeing T3171 fail with incorrect stderr output on Darwin (e.g. https://circleci.com/gh/ghc/ghc/7106):
Actual stdout output differs from expected:
--- ./ghci/should_run/T3171.run/T3171.stdout.normalised 2018-07-14 21:24:25.000000000 -0700
+++ ./ghci/should_run/T3171.run/T3171.run.stdout.normalised 2018-07-14 21:24:25.000000000 -0700

-Interrupted.
