window: Ignore geometry widget

Ignore the geometry widget passed to gtk_window_set_geometry_hints().
Usind the widget itself was a hack that complicates the size request
machinery.

It is also incorrect in that it doesn't respect height-for-width.

Last but not least, it was only used by gnome-terminal and that
application can easily work without it.
