test: further extend systemctl's sanity coverage

Also, fix a race condition introduced by d16684fe13:
```
[   16.904218] H testsuite-26.sh[394]: + systemd-run --unit failed.service /bin/false
[   16.964783] H systemd[845]: failed.service: Executing: /bin/false
[   16.965062] H systemd[1]: Started failed.service.
[   16.965462] H testsuite-26.sh[844]: Running as unit: failed.service
[   16.966390] H testsuite-26.sh[394]: + systemctl is-failed failed.service

[   16.978478] H systemd[1]: failed.service: Failed with result 'exit-code'.
