[OLEAUT32] Use snprintf instead of sprintf

Fixes GCC 8 warning:
    dll/win32/oleaut32/oleaut.c:876:39: error: '%s' directive writing up to 99 bytes into a region of size between 92 and 291 [-Werror=format-overflow=]
         sprintf(typelibkey, "Typelib\%s\%s\0\win%u", tlguid, ver, sizeof(void *) == 8 ? 64 : 32);
                                           ^~                     ~~~
    dll/win32/oleaut32/oleaut.c:876:5: note: 'sprintf' output between 18 and 316 bytes into a destination of size 300
         sprintf(typelibkey, "Typelib\%s\%s\0\win%u", tlguid, ver, sizeof(void *) == 8 ? 64 : 32);
         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
