checkkeys: Create a renderer for window display on Wayland On Wayland -- or at least on some Wayland implementations -- windows aren't shown until something has been rendered into them. For the 'checkkeys' test program, this means that keyboard input isn't registered, making the program rather useless. By creating a renderer and presenting once, the window is properly displayed, and the test behaves as it does under X11 (including XWayland). The exact same thing was done with testmessge in 1cd97e2695 (PR #4252)
