Align the podman ps --filter behavior with docker

All of our filters worked exclusive resulting in `--filter status=created --filter status=exited` to return nothing.

In docker filters with the same key work inclusive with the only exception being `label` which is exclusive. Filters with different keys always work exclusive.

This PR aims to match the docker behavior with podman.
