Add systemd circular dependency check
It's usefull add circular dependency check for systemd units.
The error log if had circular dependency:
```
Mar 10 06:20:45 g220b systemd[1]: xyz.openbmc_project.AssetManager.service: Found ordering cycle on xyz.openbmc_project.Software.BMC.Updater.service/start

Mar 10 06:20:45 g220b systemd[1]: Queued start job for default target Multi-User System.
```
I think this is good to check it in CI.
Tested:
```
~# python3 -m robot -v OPENBMC_HOST:xx.xx.xx.xx redfish/test_xit.robot
