remove the py26 dependency on python-future

[bukzor]

Python-future is problematic because of PythonCharmers/python-future#148

When I add codecov to my python project, my py26 test suite starts failing because of this above bug and my new transitive dependency on python-future.

Testing done:

$ tox                                                                                                                                    [34/2331]

I don't believe this patch broke appveyor/windows. Is that possible?

[bukzor]

I believe appveyor is simply broken for master branch.
It most recently passed more than four months ago: https://ci.appveyor.com/project/stevepeak/codecov-python/history
