Gtk3: Add background class to tooltips

This CL fixes the tooltip background color on the non-Dark variant of
Adwaita which requires tooltips have the "background" class [1].

Additionally, this CL avoids creating a selector with a GtkWindow
parent class on Gtk 3.20.  This avoids tinting the tooltip with the
window background color if tooltips have transparency (FYI: Chrome
tooltips are opaque, so the alpha will be ignored).
