Move initial root contents into a hook. This is a necessary but not complete step towards supporting Fedora and Suse distributions. Further work is needed (e.g. to quiesce daemons on installation). Change-Id: If3ea6093d41a21de755db52328226b84b5a3ede6

# These are useful, or at worst not harmful, for all images we build.
Enable --offline support for Ubuntu root images. When --offline is set elements should not revalidate cached data. The ubuntu element had not been updated to match this. SHA checking is also skipped as we only move a new cached file into place when the hash matches, and we might download a new hash before updating the image cache, which would cause persistent --offline failures.

Make Ubuntu 13.04 (raring) the default release Ubuntu 13.04 has been released now for 3 months.

Build images using loopdev instead of qemu-nbd. Qemu-nbd does not perform well with older versions of qemu due to the lack of writeback caching mode. It also only builds qcow2 images and there is a desire for raw image support. Finally, qemu-nbd makes it very difficult to build images concurrently due to the somewhat opaque nature of how it selects a /dev/nbd# device. losetup, on the other hand, makes this process very straight forward.
