Platform preferences do not update on newer KDE systems

[Thiago Milczarek Sayão]

Some settings are synced between gnome and kde, but the gtk theme seems to
not be.

Probably because that is not guaranteed that gtk will have the same kde
theme option 1:1.

On my KDE Testing VM, there is a gtk theme option on Global Theme -> System
Application Style -> Configure GNOME/GTK Application Style.

Gtk maps dconf setting /org/gnome/desktop/interface/gtk-theme to the
gtk-theme-name signal.

You can see it change with:
dconf watch /org/gnome/desktop/interface/gtk-theme
