The organization in rustbuild was a little odd at the moment where the `lib.rs` was quite small but the binary `main.rs` was much larger. Unfortunately as well there was a `build/` directory with the implementation of the build system, but this directory was ignored by GitHub on the file-search prompt which was a little annoying. This commit reorganizes rustbuild slightly where all the library files (the build system) is located directly inside of `src/bootstrap` and all the binaries now live in `src/bootstrap/bin` (they're small). Hopefully this should allow GitHub to index and allow navigating all the files while maintaining a relatively similar layout to the other libraries in `src/`.
