Don't call undefined function elisp-eldoc-documentation-function (bug#42493)

Browse source 
* lisp/ielm.el (inferior-emacs-lisp-mode): Add
`elisp-eldoc-var-docstring' and `elisp-eldoc-funcall' as
`eldoc-documentation-functions' instead of the undefined
elisp-eldoc-documentation-function (bug#42493).
