The nixpkgs-unstable channel's programs.sqlite was used to identify
packages producing exactly one binary, and these automatically added
to their package definitions wherever possible.
The original ronn has long been unmaintained.
Let’s switch to the same fork Alpine and Debian use,
since there are projects expecting ronn to support
command-line arguments introduced by this fork.
