page.c: Ensure trailing '/' on dir download URLs

Otherwise, it is not ensured web browsers would translate a relative
directory such as "dir/.." to a URL with a trailing '/'. Therefore, a
POST request to "/user?download=1" would fail because slcl only
considers "/user/" (note the trailing '/') as valid.
