Re-enable a couple of evaluator tests.

These tests had been disabled as part of
b7742c6b71 ("new evaluator, y'all").

* test-suite/tests/eval.test ("define set procedure-name")["closure"]:
  Change to `pass-if' since it now works, as a result of
  ee15aa46e3 ("set names of functions
  defined at the toplevel from `eval'").
  ("stacks")["arguments of a gsubr stack frame"]: Remove (throw
  'unresolved).
