popover: Add private _gtk_popover_set_apply_shape() call

Browse Source 
Popovers no longer sets a shape, unless this function is called. This
function exists so widgets that are potentially placed on top of other
native windows can get a popover that's nicely shaped, even if it has
no border shadow around.
