Use the SATA HDD controller for faster disk IO speeds on VirtualBox

According to the virtualbox documentation: Like a real SATA controller, VirtualBox's virtual SATA controller operates faster and also consumes fewer CPU resources than the virtual IDE controller. Also, this allows you to connect up to 30 virtual hard disks to one machine instead of just three, as with the VirtualBox IDE controller (with the DVD drive already attached). This has been an option in Packer for a while now: hashicorp/packer#391 like so: "hard_drive_interface": "sata",
