Fix typo in rb_class_real doc

[S-H-GAMELINKS]

Hi.

I found typo in object.c(but, I'm not sure that was correct)

 * \return the ancestor class found, or a falsey value if nothing found.

falsey is false typo?

I think it isn't a typo, but simply wrong.
While it seems to intend false or nil, that return value can't be Qnil as it causes a segfault in that case.

So, it's fix like this?

return the ancestor class found, or Qfalse if nothing found.

Yes. RCLASS_SUPER is rb_class_get_superclass. Note that Qfalse is 0 in C.
