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
There is a wide variety of tracing options through the various shell
scripts. Some use "set -eux", others explicity set xtrace and others
do nothing. There is a "-x" option to bin/disk-image-create but it
doesn't flow down to the many scripts it calls.
This adds a global integer variable set by disk-image-create
DIB_DEBUG_TRACE. All scripts have a stanza added to detect this and
turn on tracing. Any other tracing methods are rolled into this. So
the standard header is
---
if [ "${DIB_DEBUG_TRACE:-0}" -gt 0 ]; then
set -x
fi
set -eu
set -o pipefail
---
Multiple -x options can be specified to dib-create-image, which
increases the value of DIB_DEBUG_TRACE. If script authors feel their
script should only trace at higher levels, they should modify the
"-gt" value. If they feel it should trace by default, they can modify
the default value also.
Changes to pachset 16 : scripts which currently trace themselves by
default have retained this behaviour with DIB_DEBUG_TRACE defaulting
to "1". This was done by running [1] on patch set 15. See the thread
beginning at [2]
dib-lint is also updated to look for the variable being matched.

The docker build folks obsess about image size and speed a bit. Grab a
few of their optimizations from their debootstrap build process and
apply them to ours.
