Log Message:
During awaitkey(), move the cursor back to the beginning of the
countdown with '\b' only after waiting.
Some UEFI implementations have a destructive/erasing backspace,
and will not show the countdown if we move the cursor back before the
wait.
My ThinkPad T430 w/ Lenovo's UEFI exhibited this whiteout-backspace,
while my Gigabyte Brix GB-BXBT-2807 did not.
Should fix PR #53292.
