disable autocrlf on Windows jobs

Summary:
In D36905191 (6e6bf12f62), getdeps gained the ability to apply patches on Windows.

However, on GitHub Action workers, `core.autocrlf` is turned on by default. This means the patch files we checked in will end up having CRLF endings while the source code we downloaded are still in LF endings, and `git apply` doesn't like that.

This diff teaches getdeps to disable `core.autocrlf` in GitHub Action Windows workers.
