W0611 unused-import false positive

[teake]

This one seems related to #3444.

Steps to reproduce

1. Make a Python file (w0611.py) with the following content:

from os import environ

for k, v in environ.items():
    print(k, v)

2. Run pylint --disable=all --enable=W0611 w0611.py

Current behavior

Output:

************* Module w0611
w0611.py:1:0: W0611: Unused environ imported from os (unused-import)

-------------------------------------------------------------------
Your code has been rated at 6.67/10 (previous run: 10.00/10, -3.33)

Expected behavior

That W0611 isn't raised.
