ps2: fix scancodes sent for Ctrl+Pause key combination
The 'Pause' key is special in the AT set 1 / set 2 scancode definitions. An unmodified 'Pause' key is supposed to send AT Set 1: e1 1d 45 91 9d c5 (Down) <nothing> (Up) AT Set 2: e1 14 77 e1 f0 14 f0 77 (Down) <nothing> (Up) which QEMU gets right. When combined with Ctrl (both left and right variants), a different sequence is expected AT Set 1: e0 46 e0 c6 (Down) <nothing> (Up) AT Set 2: e0 7e e0 f0 73 (Down) <nothing> (Up) Signed-off-by: Daniel P.
