ssl: load CA certificates from system's store by default on Python 2.7.9

This will make it easy to manage in-house CA certificates, which are often
used in corporate environment and installed into the Windows' certs store.

Unlike Apple python, the dummycert trick isn't necessary on Python 2.7.9.
The default web.cacerts will be set as follows:

  environment    web.cacerts  behavior
  -------------  -----------  -----------------------------------------
  Apple Python   dummycert    fall back to system's store
  Python 2.7.8   '!'          never use CA certs (show warning instead)
  Python 2.7.9+  None         load CA certs from system's store
