add missing lambda defs per #5509
...
the result is now unknown because the nested expression contains exists, which doesn't get replaced by universal quantifier which is assumed by the legacy core.
The legacy core should not depend on universal quantifiers only, but fixing this is a risk. Workaround is to rewrite goals using forall only (replace exists by de-Morgan dual).

mb-skolem for arithmetic with model repair
...
The contract is that users of mb-skolem ensure that
interface equalities are preserved (by adding a
sufficient set of disequalities, such as a chain
x1 < x2 < x3 .., to force that solutions for
x_i does not clash).
