Title: xfreerdp: fix xf_GetWindowProperty

xf_GetWindowProperty should return False if the specified property does not exist.
It is not sufficient to simply check for the return value of XGetWindowProperty.
XGetWindowProperty also returns Success if the specified property does not exist.
However, it will return "None" to the actual_type_return parameter in that case.
This change fixes several crashes with some (exotic) window managers.
