Clean-up some now unnecessary diff against master

Clean-up some now unnecessary diff against master

	* lisp/emacs-lisp/autoload.el (update-directory-autoloads):
	.eln files have been moved so remove the '.eln' match.

	* lisp/emacs-lisp/bytecomp.el (byte-compile-refresh-preloaded):
	Likewise.

	* lisp/emacs-lisp/find-func.el (find-library-suffixes): Clean-up
	as '.eln' is no more in `load-suffixes'.

	* lisp/help-fns.el (find-lisp-object-file-name): Clean-up as
	`symbol-file' will return the '.elc' file.

	* src/lread.c (Fget_load_suffixes): Remove logic as '.eln' is not
	anymore in load-suffixes.
	(openp): Two spaces.
