runtests.pl: reapply accidental revert

Reapply an accidental, and unrelated, change committed in
3c128966edc86c89de85f72671f9f627c984af53 which unwantedly reverted
the preceding commit fcd5c2baffff95b858b43bfbc3d03dac2ef1b5ce.

Caused by doing a local rebase when `git am` did not apply cleanly,
and most likely using a local base behind master.
