Run OFRAK on MacBook with M1 chip

[whyitfor]

What is the use case for the feature?
I would like to be able to run OFRAK on my MacBook with the M1 chip.

Does the feature contain any proprietary information about another company's intellectual property?
No.

How would you implement this feature?
Ensure that Docker image can be built and run on this platform. Additionally, ensure that the Python install of OFRAK on the target platform works.

Non-comprehensive fixes and issues that I've run into while using OFRAK on an M1 Mac:

• Need to add apt-get cmake to ofrak_core's Dockerstub.
• Running Docker containers as ARMv8 led to issues with Toolchain. LLVM unsupported and using GNU led to insufficient space issues during patch making. Forcing LLVM to run ARMv8 led to it attempting to use an x86-64 library.
• In order to run Docker as AMD64, need to:
  • Add FROM --platform=linux/amd64 in build_image.py where the Dockerfile parts are specified.
  • Set ARG TARGETARCH="amd64" in ofrak_patch_maker's Dockerstub.
• Pip segfaults when attempting to build Docker images with any Python > 3.7.

On M1 I ran into issue installing orjson, which wanted rust to build from source a dependency. Upgrading pip python3 -m pip install --upgrade pip to 23.0 resolved this issue.

Running pip install ofrak also ran into issues with xattr==0.9.7 (because of cffi) -- updating to xattr=0.10.1 resolves that issue (this comes with #217).

With pip install ofrak, installing lief also ran into issues (cmake was not installed), since there is not a 3.8 wheel available.

I also needed to brew install libmagic.
