Dockerfile, cmake: Simplify build (#111)

* Dockerfile, cmake: Simplify build

Always use clang in the Dockerfile, and don't overspecify
the build type.

Additionally, drop -Weverything when building in Debug mode --
it has competing flags internally and isn't intended for actual
builds.

* Dockerfile: Set CC and CXX

Ensures that we build with clang(++).

* python/setup: Blacken
