Set rawimage for containers created via play kube

[machacekondra]

This commit set the containers RawImageName to default image name
specified in Pod YAML, so the containers could be used via autoupdate
feature, which needs the RawImageName to be set.

Currently RawImageName is set only for the create/run/clone podman
commands.

Previously if auto-update command was executed on containers created by podman play kube we got ouput:

$ podman auto-update --dry-run
UNIT                     CONTAINER                       IMAGE                                 POLICY      UPDATED
Error: registry auto-updating container "7f519304b0081d142b8f1802a50ed0ce7832bcc6862b44e12bd9510120b93c41": raw-image name is empty

LGTM but note that auto-update does not support containers created via play kube.

I was just about to ask this.

@machacekondra You have to rebase to the latest main to fix the windows build test.

Well, the only way I was able to make it work via play kube was:

apiVersion: v1
kind: Pod
metadata:
  name: mypod
  labels:
    io.containers.autoupdate: registry
    PODMAN_SYSTEMD_UNIT: mypod.service
spec:
  containers:
    - name: test-container
      image: quay.io/bitnami/nginx:latest

The labels are propageted here: https://github.com/containers/podman/blob/main/pkg/domain/infra/abi/play.go#L440
The only problem is that we need to set manually PODMAN_SYSTEMD_UNIT, so we need to know the name of the service in advance.
