Unset PYTHONPATH before calling pants

Our tests are started via `./pants test.pytest` and are then calling `./pants binary`
within some test setup routines. Looks like that the `PYTHONPATH` can be tainted for
the second run. Unsetting it seems to prevent test failures of the kind:

```
Traceback (most recent call last):
File "/home/jenkins/.cache/pants/setup/bootstrap-Linux-x86_64/0.0.80/bin/pants", line 7, in <module>
 from pants.bin.pants_exe import main
ImportError: No module named pants.bin.pants_exe
```
