`express-session` fails on Windows

[targos]

See https://ci.nodejs.org/job/citgm-smoker-nobuild/1723/ for example.

It looks like the test script is not made to support Windows.

I can take a look later, I’m also a maintainer of that package.

@targos how can i know if the change i'm making will actually work here?

Should I open a PR changing the SHA so you can run CITGM and check if it works?

I see that the script does bash test/support/gencert.sh. @StefanStojanovic do we have WSL on the CI hosts?
