Xiangyu Chen e31be0b0e6 systemd-systemctl: fix dead loop when multi services enable each other ...

libvirt has added a feature that all sockets for a service being enabled when a single
one of them is enabled since 9.9.x[1], it likes serviceA enable serviceB, serviceB enable
serviceA, that cause our systemctl script trap into a dead loop in postinstall stage,
the error message as below:

Traceback (most recent call last):
  File "/usr/lib/python3.8/pathlib.py", line 722, in __str__
    return self._str
AttributeError: _str

During handling of the above exception, another exception occurred:
