qemu data path small fix

[revelator]

The windows version expects data to be in the same dir as the qemu executable so i came up with a small fix. `diff -urN qemu-2.9.0.old/os-win32.c qemu-2.9.0/os-win32.c --- qemu-2.9.0.old/os-win32.c 2017-04-20 16:57:01.000000000 +0200 +++ qemu-2.9.0/os-win32.c 2017-07-27 11:21:36.421593700 +0200 @@ -77,11 +77,48 @@ atexit(os_undo_timer_resolution); }
