* Fix for podman usage
The output of load command in docker and podman differs:
- docker produces only one line of output the sha256 hash at 4th position
- podman produces mulktiple lines of output with sha256 hash in the last line at third position
This patch filters the line with hash and print the last argument, which is the hash. It works with docker and podman.

Change the mkimage script so that the produced image is
reproducible. This involves:
- removing the ldconfig aux-cache as it changes on every build.
- set the mtimes of the files to a specific date so that the
resulting tar file will have the same contents.
- The `strings` guard around the unsafe-io tweak seems to be
non-deterministic. It was sometimes not adding the tweak
for the same file. Remove it as we don't care about older
than jessie.
- Importing the image by constructing a docker image with
a specific timestamp and doing `docker load`.
Also change the buildall script to build each image twice and
confirm that the same tarball is produced, and that results
in the layers in the imported images matching.
Add a dockerdiff script that checks that two images are equivalent,
and tries to show the differences if not. This is useful when the
build script reports differences, as it can point to what the
differences are.
