Include queried facts as host vars in -A inventory

`-A` emitted hosts with empty vars, so `-F ipaddress,enc_role -A` lost the facts
it just queried. Ansible inventories are far more useful with the values inline.

- Extract factsByHost() (the {host: {fact: value}} builder) and share it between
  -j and -A so the Ansible inventory attaches each host's queried fact(s) as
  host vars, keyed by real fact name.
- Strengthen the Ansible test to assert host vars and add a multi-fact case.
