systemd: replace multi-user with default.target

Replace `multi-user.target` with `default.target` across the code base. It seems like the multi-user one is not available for (rootless) users on F35 anymore is causing issues in all kinds of ways, for instance, enabling the podman.service or generated systemd units. Fixes: containers#12438 Signed-off-by: Valentin Rothberg <[email protected]>

 `busctl-monitor` is almost usable in `RHEL 8`, except that it always outputs two bogus events when it starts up,
 one of which is (in its only machine-readable format) indistinguishable from the `NameOwnerChanged` that you get when firewalld starts up.
