James Slagle 07c22185bd Use package-installs in more elements
Updates additional elements in diskimage-builder to use the declarative
package install support provided by the package-installs element.
package-installs does not yet support the pkg-map functionality, so
elements using pkg-map are not migrated. That support will come in the
near future.

# When partition staging is moved to a separate stage, this will need to happen

# hypervisor kernel + ramdisk, and fixed up by 51-grub for vm images.
