    shell,plugin: Set position of GtkPopover. Fixes 756976
    
    On wayland, the GtkPopover is shown in Gtk's default position which is
    GTK_POS_TOP. This default makes Evince unusable when having the window
    maximized. Besides that it looks ugly having the popups shown in the
    top of the window.
