Enable auto-rootdisk growth on gce-backports.

This commit adds the cloud-initramfs-growroot package to the
installation list for GCE images with backports enabled, and updates
the gce tasklist to add the /etc/init.d/expand-root script
(with provider-appropriate touch-ups) to the image.

Allow mixed kernel/userspace architecture.

This is to allow building an image for a 64bit machine but with 32bit userspace.

Probably not a common usecase but ideal if you need to address more higher quantities of memory but cant migrate to a full 64bit userspace due to something like ruby eating twice as much memory.
