If by one line you mean one command you can use a heredoc:
kubectl apply -f - <<EOF
apiVersion: v1
kind: ServiceAccount
metadata:
name: test-role
namespace: utility
annotations:
eks.amazonaws.com/role-arn: arn:aws:iam::xxx:role/rolename
EOF
Using the imperative kubectl commands, requires running two commands:
kubectl -n utility create serviceaccount test-role
kubectl -n utility annotate serviceaccount eks.amazonaws.com/role-arn=arn:aws:iam::xxx:role/rolename
