salt: 2016.3.3 -> 2016.11.2 for multiple CVEs

From the Arch Linux advisory:

- CVE-2017-5192 (arbitrary code execution): The
  `LocalClient.cmd_batch()` method client does not accept
  `external_auth` credentials and so access to it from salt-api has
  been removed for now. This vulnerability allows code execution for
  already- authenticated users and is only in effect when running
  salt-api as the `root` user.

- CVE-2017-5200 (arbitrary command execution): Salt-api allows
  arbitrary command execution on a salt-master via Salt's ssh_client.
  Users of Salt-API and salt-ssh could execute a command on the salt
  master via a hole when both systems were enabled.
