Somewhere in the Podman v2 rewrite, we allowed
`podman start --attach` to print the container ID of the started
container after exiting from the attach session (via detach key
or the container exiting naturally). We should never print the ID
when `--attach` is given, which makes the fix simple - make the
print statement conditional on `--attach` not being present.
Wierdly, this only happened with `--interactive` was given to
`podman start`. I don't know why that is, but this resolves the
issue without having to dig any deeper, so I'm content.
Fixes#7055
