Everywhere: Remove everything non-essential for "make clean all"

This commit removes everything not strictly necessary for running
"make clean all" inside jw-build.

packaging jw-devtest. This cuts the repo down from 24077 to 4725
lines of code.

The idea is to

1) Further remove bloat from the remaining bits

2) Re-add what's necessary to build and package other essential repos.

   The decision should be based on whether or not jw-build can also be
   useful in a non-janware context.
