We have #if-ery on Q_OS_DARWIN controlling an expectation of gettign
"GMT+1" and "GMT+2" instead of "CET" and "CEST" in two tests; this
turns out to not be a deficiency of macOS so much as of how we
configure Coin's VMs. While we fix that, we need to ignore failures
in these tests, so that we can pull the #if-ery out and clear the
blacklist once the VMs are set up properly.
