[issue8391] os.execvpe() doesn't support surrogates in env

STINNER Victor added the comment: I blocked the fix in Python 3.1 because it's non trivial and I prefer to avoid complex changes in Python 3.1. But then I realized that Python 3.1 has two bugs about environment variables. It uses sys.getfilesystemencoding()+surrogateecape to decode variables

[issue8391] os.execvpe() doesn't support surrogates in env
