test: ignore EC from the second `systemctl status -a` as well

There is a TOCTOU in the `systemctl status` where a unit might change
its state during the initial ListUnitsByPatterns call and the subsequent
individual GetAll calls, which then makes the systemctl call fail even
if the unit that was originally pulled in was active/running:
