  1. Allow tests to run in parallel 

    This commit edits tests to allow tests to run in parallel instead of taking
global locks. This works by avoiding `env::set_current_dir` and instead tracking
the current directory in the `Config` structure, where all child processes get
an updated cwd.

  2. Improve test performance with smaller binaries 

    Test runtime is almost completely dominated by xz, gz, and sha256 of all the
tarballs that are created. "Hello world" for Rust is a few MB right now on
Linux, so slim it down massively through the use of `strip`. Also use `Arc` and
hard links where possible instead of full copies.

  3. Cache tarball creation in tests 

    No need to re-zip everything!
