Fix nonsensical universe abstraction in the kernel.
The function turning a side-effect declaration into the corresponding
entry was crazily wrong, as it used a named universe context quantifying
over DeBruijn universe indices. Declaring such entries resulted
in random anomalies.
This fixes bug #5641.
