InvalidParameter on IAM Role and Policy

[dannyrandall]

The default aws_iam_path_prefix parameter of "" causes a validation error on terraform apply:

Error: Error creating IAM Role k8s-av-alb-ingress-controller: InvalidParameter: 1 validation error(s) found.

It seems like path has to at least have a length of 1 to be valid. There are two possible solutions I can think of:

1. Change the default aws_iam_path_prefix to "/" like it is in the terraform documentation
2. Change the default aws_iam_path_prefix to null, and only set the path value if a path prefix was passed in.

I'm happy to make a PR if that would help.
