python: 2.7.9rc1 devel

ensurepip is backported to 2.7.9; use that to get pip instead of staging pip and setuptools ourselves.
Ah yes, I forgot about the fact you're forcing an uninstall. We don't have a way to regenerate the scripts, maybe we should?

For the record, the scripts we install (when install from Wheel) looks like this:

```python
#!/Users/dstufft/.virtualenvs/tmp-3c7b2035bdf4042/bin/python3.4
# -*- coding: utf-8 -*-
import re
import sys

from pip import main

if __name__ == '__main__':
    sys.argv[0] = re.sub(r'(-script\.pyw|\.exe)?$', '', sys.argv[0])
    sys.exit(main())
```

There's nothing particularly special about them.
