Drop auth guards for input cgit never sends

cgit passes an empty string, never nil, when a request names no
repository, so the check that the index stays up proved nothing, and
auth-file in fact refuses the index too while its repos file cannot be
read. A session_seconds of 0 signs a session that has expired by the
time it comes back, so it needs no branch of its own in set_cookie.
