Fix: update OpenSSL and certificates to avoid ansible-galaxy fails due to incompatible security rules.

Evidence:

  $ ansible-galaxy install ...
  - the API server (galaxy.ansible.com) is not responding, please try again later.

@see https://twitter.com/thejimic/status/592527999695597568

  > that's odd, can you see if you can hit the API directly (browser or curl/wget): https://galaxy.ansible.com/api/v1/
