fix failing when serving over HTTP from within /root

rationale:
If we switch from root to nobody/nogroup while running in /root,
everytime simple-httpd accesses to a files while answering to urpmi will
fail with "-1 EACCES (Permission denied)"
Then t/tmp/error.log contains "Error - 404 - file not found" but that's
hidden when running tests as part of CPAN testers.
