Podman scope 单元列为 failed

Issue

如果您运行 'systemctl | grep -i failed'，会发现了一个失败的 systemd scope 单元：

[root@controller ~]# systemctl | grep -i failed
● libpod-3f61c4efc9f5f576d12e6d04b3d3b420c524392088678234857e8f5cf4736174.scope                                                        loaded failed failed    libcontainer container 

进一步检查服务显示：

[root@controller ~]# systemctl status libpod-3f61c4efc9f5f576d12e6d04b3d3b420c524392088678234857e8f5cf4736174.scope
