virtio-input: add missing key mappings

KEY_PAUSE is flat out missing. KEY_SYSRQ already has a keycode
assigned but it's not what I'm seeing on my system. The mapping
doesn't appear to have to be unique so both keycodes now map to
KEY_SYSRQ which is what the "Keyboard PrintScreen", HID usage ID
0x46, translates to.
