hgk: update backgroud colour when Ttk is available

Ttk doesn't automatically set up Tk colour palette.
Because of that, Ttk controls look differently when used
together with old Tk controls. When we use Ttk controls,
we first query if we have any setting for the client
background, and if we do, we update Tk palette as well.
