autoboot: Fix inconsistent countdown output

Commit 5f70be08b015 ("Fix autoboot countdown printing wrong") introduces
inconsistency in how the countdown is displayed. For example, in case
when BOOTDELAY=5, the next output is observed during the boot:

    Hit any key to stop autoboot:  5
    Hit any key to stop autoboot: 4
    Hit any key to stop autoboot: 3

That happens due to different printf format (%2d vs %1d). Moreover, the
mentioned commit fails to handle the case when the user is holding some
key before the countdown is shown. E.g. if BOOTDELAY=101, the next
malformed output is being produced:

    Hit any key to stop autoboot: 1 0

That's because the fast path code wasn't modified accordingly, and still
tries to erase the number using '\b\b\b' format.

Fix both issues by introducing a dedicated routine for printing the
whole countdown line.
