Hideyuki Nagase 5d939bc636 rdp: Korean keyboard support
Korean keyboards are keyboard type 8:
https://docs.microsoft.com/en-us/windows/win32/api/winuser/nf-winuser-getkeyboardtype

While type 8 is not explicitly mentioned in the RDP documentation,
it can be sent over the wire. Let's support the variants we can.
