Skip (get-unsat-assumptions) tests not supported (#1656)

(get-unsat-assumptions) requires the proof infrastructure,so we can't
run the regression tests if CVC4 has not been configured for it. This
commit changes the regression script to skip tests containing
(get-unsat-assumptions) when CVC4 has not been compiled with proof
support.
