GTK/SDL fixes for a black screen displayed by virtio-gpu | expand

Hi,

This patchset fixes black screen displayed by Qemu using virtio-gpu.
There is a race condition bug with a timer that disables display output
after it has been enabled by virtio-gpu. The problem is reproducible
by running Qemu with a disabled GL vsync. Note vsync is disabled for
SDL display by default.

  ui/sdl2: Don't disable scanout when display is refreshed
  ui/gtk: Don't disable scanout when display is refreshed
