[file-roller/wip/iainl/keypress-fixes: 311/312] fr-window: Position the Shift-F10 menu at the selected row

[Jan Tojnar <jtojnar src gnome org>]

commit a3dc1a35310f067aad767b2e23eb90e3fb81d509
Author: Iain Lane <iainl gnome org>

    fr-window: Position the Shift-F10 menu at the selected row
    
    ...rather than the location of the mouse cursor
    
    This is the approach taken by nautilus, and it means the menu is at a
    more sensible place.
    
    Requires GTK 3.22.
