Tests fail on windows due to issues in bazel-starlib

Around 16 test cases are failing with the error below. The root cause is https://github.com/cgrindel/bazel-starlib/issues/447. There is a possible fix: https://github.com/cgrindel/bazel-starlib/pull/446

```

To reproduce:
```
git clone
cd rules_bazel_integration_test
bazel test //tests/tools_tests:bzlformat_lint_test
bazel clean
bazel --windows_enable_symlinks test //tests/tools_tests:bzlformat_lint_test
bazel clean
bazel --windows_enable_symlinks test //tests/tools_tests:bzlformat_lint_test --enable_runfiles
```

Start by reproducing the failure with `bazel test //tests/tools_tests:bzlformat_lint_test` and the Windows command variants listed in the issue. Read bazel-starlib issue 447 and pull request 446 alongside the failing `bzlformat_lint_test` output; done means the Windows test cases start successfully and pass.
