WSL supports `cloud-init` for provisioning. In some cases (RHEL) this is enabled. If `wsl-setup` is used on RHEL then there's a TOCTOU between the check for "no user exists" and the "create user" part as `cloud-init` creates the user during the prompt. Let's exit early and assume everything is handled by `cloud-init` *if* it is enabled. Signed-off-by: Simon de Vlieger <supakeen@redhat.com>
