Title: BUG/BLD: exclude sandbox in relative path, not absolute

Closes https://github.com/statsmodels/statsmodels/issues/1457

I didn't see any tests for `setup.py`, so I didn't include any. I can write a test for this function in a new file if you want. I've manually tested on a Mac for python 2.7 and 3.3
