Add (semi-redundant) fix to nnatom backend declaration

* lisp/gnus/gnus.el (gnus-valid-select-methods): We need a value for
post/mail/none in order to conform to the option type.
* lisp/gnus/nnatom.el: This call to gnus-declare-backend does the exact
same thing as above, and needs to be adjusted accordingly.
