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 uses systemd-run to setup transient systemd timers, e.g. for healthchecks.
On systems where systemd is not present in /run/current-system/sw/bin or ~/.nix-profile/bin (like one of my Ubuntu hosts), setting up the transient timers will fail. For containers with healthchecks configured, this results in the container being stuck in starting state.
Relevant issue here: containers/podman#25034
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
Adds a new Podman module for creating user containers and networks as
systemd services. These are installed to the user's
`$XDG_CONFIG/systemd/user` directory.
