Right now dib-python works by trying to find any python on a system in
an order of precedence. A much better way is if we are explicit about
the python we intend to be there which will allow us to make better
decisions in other elements (such as allowing for package-installs to
take into account DIB_PYTHON_VERSION) as well as allow for users to
specify a preferred python version.

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.
