[PATCH gtk-vnc] vncdisplaykeymap: Use XkbGetMap and XkbGetNames instead of XkbGetKeyboard

[Pavel Grunt <pgrunt redhat com>]

XkbGetKeyboard does not work in XWayland (bfo#89240).

Hi, I know that gtk-vnc is already working in XWayland, but the check for XWayland relies on the environment 
variable "WAYLAND_DISPLAY".
We solved the "XWayland keymap issue" in spice-gtk by using XkbGetMap and XkbGetNames instead of 
XkbGetKeyboard.
