Resolve "Keyboard layout wrong on remote host"

Set initial keyboard layout according to actual layout on client side. The layout is usually used when a new session is created remotely and ignored by Microsoft's RemoteFX servers. The layout is also used by xrdp.

The mapping between local keyboard layouts and those expected by FreeRDP might be inaccurate and some are still missing since I've not found the correct ones. These needs to be added yet.
