Adds build_path checks for deb pkg reprotest

In #231 we noticed that the filesystem path used to build the debian
packages was breaking reproducibility. That's due to the filepath being
recorded inside `direct_url.json`, as stipulated by PEP610.

Also relevant is PEP427, which describes the `RECORD` file for wheels.
Here we remove that file, as well, to ensure full reproducibility
regardless of path.
