[PATCH 3/7] commands: fbtest: add flush for single pattern

[Ahmad Fatoum <a.fatoum@barebox.org>]

The single-pattern else-branch calls gu_screen_blit() to copy the render
buffer to the framebuffer in-memory image, but never called fb_flush()
to make sure the image makes it to display RAM.

Add fb_flush(sc->info) after gu_screen_blit(), matching the cycling
path above.
