flux build kustomization --dry-run still tries to talk to the server

[arbourd]

Describe the bug

#3317 implemented a --dry-run flag that states:

If implemented user will be able to use flux build kustomization without any connection to the cluster.

This seems to be incorrect:

$ flux build kustomization base --path clusters/stg --kustomization-file clusters/stg/base.yaml --dry-run
✗ kubernetes client initialization failed: Get "https://kubernetes.docker.internal:6443/api?timeout=32s": dial tcp 127.0.0.1:6443: connect: connection refused

Steps to reproduce

1. Run flux build kustomization with a dead kubeconfig and watch it fail.

Expected behavior

Should render some yamls.
