path is stubbed out too aggressively

[eakuefner]

I have code that looks like this:

import os

from mymodule import path

print path.MyAwesomeMethod

When I try to unit test it inside of a fake_filesystem_unittest.TestCase, I get:

    ...
    File ".../pyfakefs/pyfakefs/fake_filesystem.py", line N, in __getattr__
  KeyError: 'MyAwesomeMethod'

However, changing the import in the snippet to from mymodule import path as path_module avoids this, which indicates that pyfakefs is stubbing out any module named path, where if possible it should only stub out os.path.
