Yukihiro "Matz" Matsumoto ddefcea151 mruby-eval/eval.c (f_instance_eval): skip mrb_value to get singleton ...

Use mrb_singleton_class_ptr() instead of mrb_instance_class(), because
the former returns NULL, when the latter raises error for immediate
objects.

```
1.instance_eval <<END
  def foo
    :foo
  end
END
```
