fix "lexical vars are collectable" test

* test-suite/tests/gc.test ("gc"): Fix "lexical vars are collectable"
  test.  (Previously, the binding was getting inlined, so we weren't
  testing what we meant to test.  Besides that, the value was a
  constant, not a closure, so it wasn't collectable in the first place!)
