docker_build: workaround the lack of LZMA in python 2.7

Some debs file actually does use the LZMA compression and reading
that format requires python 3. Backports of LZMA to python 2 are
using native deps which might be hard for the user to setup and
our support of python 3 is not really functional (it needs 2to3
to use gflags for instance). Until we fix Bazel's python 3 support,
we shell out to xzcat for supporting LZMA compressed file.

Also added test for the archive library. These tests shows some
wrong handling in the AR format padding, fixed.

Bazel (Alpha)

{Fast, Correct} - Choose two

Bazel is a build tool that builds code quickly and reliably. It is used to build the majority of Google‘s software, and thus it has been designed to handle build problems present in Google’s development environment, including:

  • A massive, shared code repository, in which all software is built from source. Bazel has been built for speed, using both caching and parallelism to achieve this. Bazel is critical to Google's ability to continue to scale its software development practices as the company grows.

  • An emphasis on automated testing and releases. Bazel has been built for correctness and reproducibility, meaning that a build performed on a continuous build machine or in a release pipeline will generate bitwise-identical outputs to those generated on a developer's machine.

  • Language and platform diversity. Bazel's architecture is general enough to support many different programming languages within Google, and can be used to build both client and server software targeting multiple architectures from the same underlying codebase.
