Fix test roles linting

Not sure if the issue is on molecule or ansible-lint or
ansible-lint precommit but currently ansible-lint is failing
at syntax-check[specific] due to unable to find the role
roles.${driver}plugin when looking at the tests/test.yml
generated by the galaxy skeleton (patched by molecule to
include the namespace):

---
- hosts: localhost
  remote_user: root
  roles:
    - roles.dockerplugin

Given that this file is neither what we want to test nor
something the plugins created, just kill it.
