find-library-name fails if file (with no extension) exists.

[Juanma Barranquero]

This change from one year ago has an unintended side effect: Emacs
finds the wrong file if a file exists in the path with the same name
and no extension, though the link pointed explicitly to the .el file.

       * emacs-lisp/find-func.el (find-library-name): Also strip
       extension if library name ends in .el, to take advantage of
       `find-library-suffixes'.

My case: I have nxml-mode installed on site-lisp, and it contains a
file named "VERSION". If I do "M-x describe-variable emacs-version
RET", move onto the "version.el" link and hit enter, Emacs finds
"VERSION" and complains "Unable to find location in file".

I can understand

 (find-library-name "version") => /my/site-lips/VERSION

but

 (find-library-name "version.el") => /my/site-lisp/VERSION

is beyond weird.
