hwdb-test: don't rely on --root= quirk

Previously, the test would rely on the fact that systemd-hwdb would
follow symlinks outside of the --root= hierarchy. That's a bug however,
and systemd-hwdb shouldn't do that. Hence let's remove the fact that the
test relies on it, so that we can then fix systemd-hwdb (specifically:
conf_files_list()) accordingly.
