vboot_display: Keep track of displayed screen
Vboot needs to track the currently displayed screen so when it needs to
change the locale or display the debug overlay it knows which screen to
redraw. Currently only the legacy path is doing this so change the new
path to update the current screen if it is successfully drawn.
BUG=chrome-os-partner:49766
BRANCH=glados
TEST=boot on glados in dev mode, hit tab and ensure screen does not go black
