Build fails in patching on Windows

Building with bazelisk on Windows 11 in git bash. This is after installing GNU `patch` and hardcoding the Python3 path:
```
kschzt@laptop MINGW64 /c/src/reclient (main)
$ bazelisk build --config=clangscandeps //cmd/...
Starting local Bazel server and connecting to it...

Reproduce the failure with `bazelisk build --config=clangscandeps //cmd/...` on Windows 11 from Git Bash. Start at WORKSPACE:336 and inspect third_party/patches/opencensus-go-exporter-stackdriver/opencensus-stackdriver-interval.patch alongside the reported patch application error. Done means the dependency fetch and requested build complete successfully on Windows.
