systemdgen: add --ignore flag to generic services

Browse Source 
The --ignore flag lets Podman ignore errors when a specified container
does not exist (anymore).  That's a nice addition to generic services
generated via the --new flag.  Those services create new containers and
can hence allows user to manually remove a container; may it only be by
accident.

The important part of using the --ignore flag is that Podman will exit 0
which plays nicer with most restart policies; a non-zero exit may yield
systemd to restart the entire service which is arguably wrong if the
user manually deletes the container.

If desired, users can still alter the generated files.
