flux2: flux build/diff: fs-security-constraint error

Describe the bug

When running flux build ..., an error is shown that indicates security issue. For example:

flux build kustomization my-app --path ./corpsol --kustomization-file ./corpsol/kustomization.yaml

will display the following error

✗ kustomize build failed: fs-security-constraint abs ./corpsol: path './corpsol' is not in or below 'C:\'

The kustomization.yaml looks like this

apiVersion: kustomize.config.k8s.io/v1beta1
kind: Kustomization
resources:
- helm-release.yaml
- ../../../../.common/helm_templates/flux_manifests/alert.yaml

Steps to reproduce

• Install Flux
• Run flux build kustomization my-app --path ./corpsol --kustomization-file ./corpsol/kustomization.yaml
• See the error - fs-security-constraint (no files are built)

Expected behavior

The kustomization should be built successfully, so that a preview is shown.
