Could we move this code to the mingw-check builder? I think having more than one "short" builder probably doesn't make too much sense; people in infra meeting seemed to agree.

I'm explicitly not r- this PR though since I think we need the test more than we need this change, so we can land the change in a future PR.

@Mark-Simulacrum Moved the code into the before_script: of IMAGE=mingw-check.
