Michael Smith f9fcb9f121 Fix goodbye.png not visible on idle auto-shutdown
The Allwinner /dev/disp driver resets brightness to 0 when the fd is
closed, so the screen monitor's SIGTERM brightness restore was undone
before the wrapper wrote goodbye.png. Restore brightness in the wrapper
itself, right before the framebuffer write.
