Subject: [PATCH] remove empty [] to mapRoles object in aws-auth (#606)

* remove empty [] to mapRoles object in aws-auth

Simply having ${yamlencode(var.map_roles)} in mapRoles for aws-auth
creates a empty [] at the end after adding the default roles.
Changing it to be added only when its not empty

* Update aws_auth.tf
