Cloudpickle 0.6.0 is broken on python3.4 for local functions

[tomMoral]

The pickling of local function from a module is broken on python3.4. This seems to be related to #205

The way to reproduce that is having 2 files in the same directory and launching the later command line.

mk_dynamic.py

def f():
    def g():
        return sum(range(10))

    return g

main.py

from mk_dynamic import f
from cloudpickle import dumps


print(dumps(f()))

And then calling the pickled function with the following command line

python -c "from cloudpickle import loads; g = loads($(python main.py)); print(g())"

The given output is

Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/home/tom/Work/prog/stackoverflow/bug_cloudpickle_builtins/mk_nobuiltin.py", line 5, in g
    return sum(range(10))
KeyError: 'sum'
