ps2: accept 'Set Key Make and Break' commands
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.
