[PATCH 4/7] ps2: accept 'Set Key Make and Break' commands

[Sven Schnelle <svens@stackframe.org>]

HP-UX sends both the 'Set key make and break (0xfc) and
'Set all key typematic make and break' (0xfa). QEMU response
with 'Resend' as it doesn't handle these commands. HP-UX than
reports an PS/2 max retransmission exceeded error. Add these
commands and just reply with ACK.
