Univ: correct compare_neq (fix #2703)
The earlier version was a bit too quick to answer <= while strict
constraints could still appear from remaining universes to explore.
Typical situation: compare u v when u <= v and u <= w < v.
Encountering u <= v isn't enough to conclude yet...
This means that kernels from r13719 to now in trunk, and
from r13735 to now in 8.3 (including 8.3pl{1,2,3}) couldn't accurately
detect universe inconsistencies, leading to potential proofs of False!
Oups, sorry...
