Correctly handle extended RDP keycodes

Browse Source 
The keycodes received by the FreeRDP server aren't evdev keycodes.
This patch adds the correct convertion to evdev keycodes. After the
patch all keys that are marked as extended in RDP packets become
functionnal (that's the case for the windows key).
Please note that this patch rely on some corrections that have been
pushed on the FreeRDP github tonight.
