use-file-dialog should not apply to mouse in *Completions*

[Drew Adams]

The doc string of `use-file-dialog' says "it applies to commands from
menus and tool bar buttons". That suggests that it does not apply to
command names that you click mouse-2 on in *Completions* -
e.g. `find-file-other-window' from `M-x'. However, that's what
happens: if the value is non-nil, then the file dialog box pops up. It
should not.

Please fix the variable in accordance with its doc string (menus and
tool-bar buttons only). If it's thought that users should be also able
to specify the file dialog box for *Completions* (to keep using the
mouse to pick the file), then there should be another option for that
- it's too common to want a file dialog box for menus and tool-bar
buttons but not for *Completions*.
