fix: do not create security group rules for docker+machine if docker-autoscaler selected (#1243)

## Description

The `runner_worker_ingress_rules` and `runner_worker_egress_rules` have
to be attached to the correct security group. At the moment the module
always attaches the rules to the docker machine security group which
does not exist when `docker-autoscaler` is used.
