populate: drop the shell implementation

Populate is the program in Rust only.  pkgs.populate checks its arguments,
and returns a script running the program with them as JSON.  The
arguments it took for the shell implementation, dash, jq, and
implementation, stay accepted and unused, so overrides setting them keep
working.

Copying flakes to remote targets using sudo gets refused during
evaluation, as before, by checks.nix, and by the program for specs from
elsewhere.

The jq test goes with the jq programs; the program's unit tests cover
their equivalents.
