[ci_gen_kustomize_values] Add hci-ironic template symlink

Add `hci-ironic -> hci` symlink in `ci_gen_kustomize_values/templates/`
so the `hci-ironic` architecture scenario uses the HCI network-values
template instead of falling back to the `common` template.

Without this, the `common` template hardcodes `"master": "ospbr"` in
the ctlplane NetworkAttachmentDefinition, which does not exist on the
OCP master nodes.  The HCI template correctly derives the ctlplane
master interface from the networking environment definition.
