[issue16587] Py_Initialize breaks wprintf on Windows

[STINNER Victor]

> _setmode(self->fd, O_BINARY) change was done in Python 3.2: see the issue #10841

The main reason was to be able to read binary file from sys.stdin
using the CGI module: see the issue #4953. In _O_TEXT mode, 0x0A byte
is replaced with 0x0A 0x0D (or the opposite, I never remember) which
corrupt binary files.
