emacs-module.h slight simplification

* src/emacs-module.c (emacs_init_function, emacs_subr): Move here ...
* src/emacs-module.h: ... from here, as they don’t need to be public.
(enum emacs_arity): Remove useless enum tag.  The enum value is
used in ptrdiff_t contexts.

* src/emacs-module.c (CHECK_USER_PTR): Fix typo in previous change.
