Rework Docker Image build (#741)

* Try reworking Docker image

* Fix some old behavior for building abi libraries

I don't think the result is actually usable...

* Remove most Python2 references

Still left some references to python2 for helper scripts since they
aren't tested (afaik) in CI

* Fix CI

* Remove old CMakeLists.txt and remove support for old TRAILOFBITS_LIBRARIES method of building

* Update README
