These tests use absolute directories and host leakage is granted
when cups and systemd are around. In fact there's no way these could work
in any predictable manner.

CUPS support was in fact disabled upstream since it's not required
in commit efb04936b8ad3bf313c289a522ae5832e22c1b7e

And for systemd we never handled it properly anyway.
