Reference shared infra RBAC in deployment scripts

PRI-750: update plugin repos to reference shared infra RBAC (PRI-695 follow-up)

- deployment/e2e-ci-runner-rbac.yaml: replaced duplicate manifest with
  reference comment pointing to privilegedescalation/infra/base/rbac/e2e-ci-runner-headlamp-rbac.yaml
- scripts/deploy-e2e-headlamp.sh: updated RBAC preflight comment and error
  message to reference infra path
- scripts/teardown-e2e-headlamp.sh: added RBAC reference comment

Infra RBAC is the source of truth managed by Flux GitOps. CI workflow
unchanged (Hugh owns .github/workflows/).
