fail to detect cgroup on a LXC container

## Bug Report

Please answer these questions before submitting your issue. Thanks!

### 1. Minimal reproduce step (Required)
- run tidb-server with systemd
```
[root@lightning ~]# cat /etc/systemd/system/tidb-server.service
[Unit]
Description=tidb

[Service]
Type=simple
Restart=always
ExecStart=/root/.tiup/components/tidb/v8.0.0-alpha-nightly/tidb-server
StandardOutput=journal
CPUQuota=50%

[Install]
WantedBy=multi-user.target
```

below are the cgroup directory of tidb-server. we can see in `/proc/pid/mountinfo` there is no mount of filesystem type = `cgroup` or `cgroup2`
```
[root@lightning ~]# ls /sys/fs/cgroup/cpu/lxc.payload.tispace_jujiajia-lightning/
cgroup.clone_children cgroup.procs cpuacct.usage cpu.cfs_period_us cpu.rt_period_us cpu.shares notify_on_release tasks
cgroup.event_control cpuacct.stat cpuacct.usage_percpu cpu.cfs_quota_us cpu.rt_runtime_us cpu.stat system.slice/ user.slice/

[root@lightning ~]# ls /sys/fs/cgroup/cpu/lxc.payload.tispace_jujiajia-lightning/system.slice/tidb-server.service/
cgroup.clone_children cgroup.procs cpuacct.usage cpu.cfs_period_us cpu.rt_period_us cpu.shares notify_on_release
cgroup.event_control cpuacct.stat cpuacct.usage_percpu cpu.cfs_quota_us cpu.rt_runtime_us cpu.stat tasks

[root@lightning ~]# cat /sys/fs/cgroup/cpu/lxc.payload.tispace_jujiajia-lightning/system.slice/tidb-server.service/cpu.cfs_quota_us
50000
[root@lightning ~]# cat /sys/fs/cgroup/cpu/lxc.payload.tispace_jujiajia-lightning/system.slice/tidb-server.service/cpu.cfs_period_us
100000
```

```
