    Adwaita: Make selector more specific
    
    A * selector applies to all widgets, so even GtkBox or GtkGrid - and
    most importantly GtkListBoxRow - need to recompute their style because
    of the * selector.
    
    By using a more specific one, these common cases aren't affected
    anymore.
    
    Fixes slowdowns in gtk3-demo's listbox demo and in gnome-software.
