helm: Always delete AWS iptable rules

This change causes Cilium DaemonSet postStart hook to always delete AWS
iptable rules unless `cni.chainingMode` is set to `aws-cni`.

This will result in the postStart hook being a noop in all non-AWS
deployments. Unfortunately there is no way for helm chart to know
whether it is running on AWS not in ENI mode.

This approach will make sure that we are deleting AWS-specific iptables
rules that cause issues while not requiring us to introduce new
configuration flags for users.
