win32: fix for wm_syscommand 

According to MSDN, in WM_SYSCOMMAND messages, the four low-order
bits of the wParam parameter are used internally by the system.
To obtain the correct result when testing the value of wParam,
an application must combine the value 0xFFF0 with the wParam
value by using the bitwise AND operator.
