hurd: Fix O_DIRECTORY | O_NOFOLLOW

Appending / to the path to be looked up makes us always follow a final
symlink, even with O_NOTRANS (since the final resolution is after the
'/').  In the O_DIRECTORY | O_NOFOLLOW case, we thus have to really open
the node and stat it, which we already do anyway, and check for
directory type.
