gitlab-ci: some fixes for failures on Windows

Hi,

this small patch series fixes some intermittent failures we have observed with our Windows CI runners. Furthermore, it fixes one persistent test failure in one of the Windows runners that was introduced recently via tests for git-last-modified(1).

Thanks!

Patrick
