[coqchk] Fix #5030

When encountering
```Coq
Module M : T.
...
Lemma c :...
...
Qed.
...
End M.
```
every field `c` without body in `T` but with a body in `M` is
registered as opacified in a table along with all constants
`opacified(c)` without body in the environment at this point (i.e.,
all axioms potentially used by c).

Then, when printing axioms, if `c` appears in the final environment it
is replaced by `opacified(c)` in the resulting list of axioms.
