Fix Oracle Linux 5.10 & 6.5 x86_64 boxes

Just noticed that my Oracle Linux 5.9 and 6.4 x86_64 boxes have been rolled back to 5.9 and 6.3 on [vagrantbox.es](http://vagrantbox.es).

Looks like some recently pull request messed up the `index.html`, someone did NOT do a proper rebase before making changes and sending a pull request.

Fixed now. Boxes have been moved away from Dropbox to dedicated VPS.
