Make XEmacs entry in the FAQ more contemporary

* doc/misc/efaq.texi (Difference between Emacs and XEmacs): Make
XEmacs entry in the FAQ more contemporary.  Remove part about re-using
XEmacs code; this is not likely to be relevant these days and in any
case is not a frequently asked question.  (Bug#45235)

 XEmacs was a branch version of Emacs that is no longer actively

-XEmacs last released a new version on January 30, 2009, and it lacks

 If you want to talk about these two versions and distinguish them,
 please call them ``Emacs'' and ``XEmacs.''  To contrast ``XEmacs''
 with ``GNU Emacs'' would be misleading, since XEmacs too has its
