Update the expected results to match changes in the podman generator
and fix not importing the podman stub overlay with module import
behind `mkIf` introduced in #6905.
podman's systemd generator can automatically resolve unit dependencies, so instead of us guessing these links to create them, we provide the sources during generation
Added support for build, image, and volume quadlets
Resolved test failures due to podman 5.3.0 upgrade
Replaced several instances of pkgs.podman with services.podman.package
