[Bug 2131131] [NEW] podman-compose cannot open relative file path

[Floris Luiten]

Public bug reported:

podman-compose v1.3.0 cannot resolve relative file paths when passing a
file. This is a known bug in v1.3.0
(https://github.com/containers/podman-compose/issues/1109). As far as I
can read from the release notes and replies in this issue it can be
fixed by upgrading to v1.4.0.

Steps to reproduce:

1. Install docker-compose v1.3.0
2. Run `podman-compose -f container/compose.yaml down`
3. Output:

```
Traceback (most recent call last):
  File "/usr/bin/podman-compose", line 33, in <module>
    sys.exit(load_entry_point('podman-compose==1.3.0', 'console_scripts', 'podman-compose')())
