    Perform package install outside of debootstrap

    Debootstrap only supports one apt repository to install packages from.
    As a result, we do not consider the updates repo during debootstrap
    causing us install a second kernel when we do an apt-get dist-upgrade
    during build.

    Lets use debootstrap to get us a minimal chroot, then add our repos and
    install the correct packages from the start.

    We also have to reorder the dpkg root.d scripts which configure apt so
    they run before we perform our package installs.
