Unify the rest of the beeps
Unify the rest of the beeps

In some cases we use a a single high beep to signal an error. It does not
seem important to distinguish this from any other kind of error, so just
use the existing case.

All beeping now goes through vb2_error_beep(), except for one beep in
vboot_audio.c.

We could move vb2_error_beep() to vboot_audio.c, but the beeps seem to be
a part of the UI rather than the audio system. Of course,
vb2_audio_looping() arguable is also...
