The podman healthchecks are implemented using systemd timers, this works great but it will never work on non system distros. Currently the logic always assumes systemd is available and will fail with an error, so users are forced to always run with --no-healthcheck to disable healthchecks that are defined in an image for example. This is annoying and IMO unessesary, we should just default to no healthcheck on these systems.

First, use the systemd build tag to disable it at build time if this tag is not used.
Second, use make sure systemd is used as init before trying to use healthchecks. This could be the case when we are run in a container.

[NO NEW TESTS NEEDED] We do not have any non systemd VMs in CI AFAIK.

Fixes #16644

Does this PR introduce a user-facing change?

Healthchecks are automatically disabled if your system does not run systemd. If podman is compiled without systemd build tag, healthcheck will be disabled at build time.
