bug#14366: 24.3; Python os.getlogin does not work

[rajanikanth@gmail.com]

Run python using:

M-x run-python (I used python 3.3.1). Once Python starts, run the
following:

import os
os.getlogin() and see the error

import os
>>> os.getlogin()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
FileNotFoundError: [Errno 2] No such file or directory

The above can be reproduced by running python in an emacs Shell too.

This does not happen when I run Python from normal shell (without
emacs):

Type "help", "copyright", "credits" or "license" for more information.
>>> import os
>>> os.getlogin()
