bug#13970: Default key binding in startup.el is wrong

[Xue Fuqiao]

In startup.el:

  (if (and (eq (key-binding "\C-h\C-c") 'describe-copying)
           (eq (key-binding "\C-h\C-d") 'describe-distribution)
           (eq (key-binding "\C-h\C-w") 'describe-no-warranty))
        (progn
[...]
        (insert ".
  Type C-h C-d for information on ")
        (insert-button "getting the latest version"
                       'action (lambda (_button) (describe-distribution))
                       'follow-link t)
        (insert ".")))

But the default key binding for `describe-distribution' has been moved to
`C-h C-o' since this commit:
