Quadlets does not create systemd unit for pod and services with pod

[lacosteque]

Issue Description

Quadlets does not create pod unit for systemd.
If you specify the Pod membership in the container, then it also skips and does not create systemd unit.

Steps to reproduce the issue

1. According to the documentation, I am creating a pod and a service.
2. If you remove the pod link from the container, then everything is ok.

Describe the results you received

1. With pod

$ pwd
/home/podman/.config/containers/systemd

$ ls -l
centos.container
test.pod

$ cat centos.container
[Container]
Image=quay.io/centos/centos:latest
Exec=sh -c "sleep inf"
Pod=test.pod

$ systemctl --user daemon-reload

$ ls -la /run/user/1039/systemd/generator/
ls: unable to access '/run/user/1039/systemd/generator/': There is no such file or directory

2. Without pod

$ cat centos.container
[Container]
Image=quay.io/centos/centos:latest
Exec=sh -c "sleep inf"

$ systemctl --user daemon-reload

$ ls -la /run/user/1039/systemd/generator/

-rw-r--r--. 1 podman podman 676 ноя 23 09:36 centos.service

Describe the results you expected

A systemd unit should have been created for the container and pod.
