Subject: [PATCH] fix: Work around path bug in aws-iam-authenticator

`aws-iam-authenticator` has an open issue where it will not recognize
IAM roles that include paths. This change causes the path supplied to
`var.iam_path` to be stripped when generating the `aws-auth` ConfigMap
in order to work around this.
