Add upstream patch fixing flickering bug

Accessing wayland guests with Boxes/virt-manager gives a guest which
keeps flickering. This patch fixes this.

+Subject: [spice-gtk] main: don't update display timer for unchanged config
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+With virgl, set_monitor_ready() may be called each time the scanout is
+updated to set the monitor area. This will call
+spice_main_update_display(), and keep the timer postponed even if the
+monitor configuration didn't change. Treat unchanged configuration as a
+no-op and keep configuration timer unchanged. This fixes monitor
+autoconfig with virgl (when the display is regularly updated).
+
+It also solves/avoids problems with a guest running on wayland when the
+"resize-guest" property is TRUE.
