The new test runner will evaluate all test profiles from the README.md
in parallel in separate nix-build processes.
Since we do not load all processes into one process,
this also helps saving memory.
Enforce proper naming: all paths are lowercase and hyphen-separated,
if there's a line of models (aspire, macbook-pro, thinkpad) it becomes
a subdirectory. Documentation for profiles is moved to README files in
respective directories.
Add an Org mode table that lists all available profiles and their paths.
Instead of fetching repo locally, use a Nix channel. Making hardware
profiles read-only should improve quality and amount of participation
long-term.
