[PATCH virt-viewer] Remove use of deprecated GTK style & size APIs

["Daniel P. Berrange" <berrange@xxxxxxxxxx>]

From: "Daniel P. Berrange" <berrange@xxxxxxxxxx>

The GtkStyle API has been deprecated in favour of GtkStyleContext.
Update ovBox.c to use the latter. Also replace use of the
gtk_widget_size_request API with gtk_widget_get_preferred_size.
