Relocate scripts for building machine images

This patch relocates all of the scripts for building machine images into
the "build/images/hack" directory. The purpose of this change is to
isolate the assets used to build machine images in order to make it
easier to copy CAPV's image stamper to the upstream tool.

Simply boot the VM locally with Fusion or Workstation and the machine will be initialized with cloud-init data from the `cloudinit` directory.
