ol-gnus: Prefer nnselect to nnir if available 

* lisp/ol-gnus.el (org-gnus-store-link): Use nnselect when available.

In the master branch of the Emacs repository, f103e89c1d (Add aliases
for recent Gnus nnselect changes, 2020-09-07) switched
org-gnus-store-link over to using nnselect, but that can't be ported
as is because it isn't backward compatible.  Make a similar change
that includes compatibility kludges.
