first deployment of eks/cluster will never work

[sgtoj]

Describe the Bug

Deploying new deployment of eks/cluster will fail due to the OIDC not existing. The local.eks_cluster_oidc_issuer_url will initial be an empty string. However, the cloudposse/eks-iam-role/aws module for aws-ebs-csi-driver and vpc-cni addons requires the variable even if the addons are not enabled.

Expected Behavior

The eks/cluster component should work for initial deployments.

Steps to Reproduce

1. deploy a new eks/cluster using the same snippet in the readme
