In [DebOps](https://debops.org/), it is common to have the Ansible host
inventory in a projects directory below "$HOME". This allows to have multiple
and separate Ansible environments. For such a setup, the host inventory can be
found at `$PWD/ansible/inventory/hosts` as Ansible is typically executed from
the root of the project. This patch adds support for such a layout as
fallback.
