osdep: Fix mingw compilation regarding stdio formats
I encountered the following compilation error on mingw:
/mnt/d/qemu/include/qemu/osdep.h:97:9: error: '__USE_MINGW_ANSI_STDIO' macro redefined [-Werror,-Wmacro-redefined]
#define __USE_MINGW_ANSI_STDIO 1
^
/mnt/d/llvm-mingw/aarch64-w64-mingw32/include/_mingw.h:433:9: note: previous definition is here
#define __USE_MINGW_ANSI_STDIO 0 /* was not defined so it should be 0 */
It turns out that __USE_MINGW_ANSI_STDIO must be set before any
system headers are included, not just before stdio.h.
