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.

Closes-Bug: #1637516
