Core/MMaps: Fallback to shortcut for flying units if Detour returned an incomplete path.

Fallback to shortcut for flying units if Detour returned an incomplete path. This is needed when a flying unit should fly to the floor below to reach the target, but since Recastnavigation doesn't support "jumping down" the unit would not find a path to the target.
