libpayload/keyboard: Reset to scancode set #2 on exit
If we select scancode set #1 and keep that, it can confuse Linux
with keyboards that don't return to set #2 when asked to load the
defaults. This happens for instance with various integrated Think-
Pad keyboards but was also seen with an external PS/2 one.
The chosen configuration, scancode set #2 without translation, seems
to be the default for many systems. So we can expect other payloads
and kernels to work with it.
