systemctl: fail in the case that no unit files were found
Previously systemctl died with message -bash-4.2# systemctl --root /rawhi list-unit-files (src/systemctl/systemctl.c:868) Out of memory. in the case that no unit files were found in the --root or the directory did not exist. So lets return ENOENT in the case that --root does not exist and empty list in the case that there are no unit files.
