Fix Elisp's elisp--documentation-one-liner (bug#43609)

To be backward compatible, this function must return nil when there is
a symbol at point but no documentation for it.  Before this fixed it
returned the string "<symbol-name>: nil".

* lisp/progmodes/elisp-mode.el (elisp--documentation-one-liner):
Check callback actually produced non-nil doc.
