Basebox and java updates

* Update the CentOS basebox to CentOS 6.5
* Change the Ubuntu basebox to use the latest bento box, switch to 64-bit for consistency
* Update `.kitchen.local.yml` example to reflect changes to the `java` cookbook, which no longer needs a URL but does need you to accept a license
  * Also update the WLP download URL
Thanks. Since so much time has passed since your PR (big sorry for that) I'll work in your suggestion separately.
