Unless there's a real need to use privileged access or to gather Ansible
facts upfront, we should always set "become: false" and
"gather_facts: false". In the case that only a few Ansible facts are
required, 'ansible.builtin.setup' with 'gather_subset' should be used.

As the YAML 1.2 standard dictates, boolean values should only use 'true'
or 'false' values.

This patch fixes these issues in the 'sudorule' test suite.
