compat: rewrite ckmake in Python

This rewrites ckmake in Python. I suspected that we can still
improve compilation down by making ckmake multithreaded.
I was right, and in order to make this multithreaded I picked
python and ncurses to display results. This shaves down 6
minutes for compilation of compat-drivers on 24 kernels from
25 minutes down to 19 minutes. This can likely be improved
further.
