ci: restart podman socket during setup

I'm not sure what is the exact root cause but this fixes an issue where systemctl enable --now podman.socket fails during container setup.

+ sudo systemctl enable --now podman.socket
Job failed. See "journalctl -xe" for details.

Nov 07 16:01:19 fv-az1153-970 systemd[1]: Failed to listen on Podman API Socket.

This leads to docker-compose failing as the service is not started properly

I tested this with several CI runs in https://github.com/SSSD/sssd/pull/7019 which were successful.
