 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.
