Replace writeReferencesToFile with writeClosure.
Make writeClosure accept a list of paths instead of a path.
Re-implement with JSON-based exportReferencesGraph interface provided by
__structuredAttrs = true.
Reword the documentation.

- Use testers.runNixOSTest instead of testers.nixosTest as nixosTest
has become obsolete.
- Prepare for cross-platform testing.
- Use the testScriptBin passthru'd by the references test package
inside the guest pkgs.

The build log of the following won't output `foo` as one might expect, but the
`$PATH` set by stdenv.
```nix
with import <nixpkgs> {};
runCommand "foo" { PATH = "foo"; } "echo $PATH; touch $out"
```
Please Nix CI (OfBorg) with empty set instead of null on non-linux platforms,
where NixOS tests are not supported.

Define package `testScriptBin` that contains the substituted test script.
* Add an `installCheckPhase` to check the result script with ShellCheck.
* Passthru as `references.testScriptBin` to run the
(substituted) test script directly (without VM).
* Drop the logic in build script that detects if
it is run in the Nix sandbox.
* Inline sample application; drop invoke-*.nix.
Format expressions.
* Format with `nixpkgs-fmt`.
* Use multi-line style of set patterns.
Call the samples with `callPackage`.
* Rename `sample` -> `samples`.
* Take individual packages / build helpers directly from the
set pattern.
* Define `cleanSamples` to filter out overriders such as `<pkg>.override`.
added by `callPackage`.
Passthru samples and invocation results for easier debugging.
* Passthru samples, references, directReferences
* Provide tests.trivial-builders.writeStringReferencesToFile with such
samples argument.
Derivations built with `writeShellScriptBin`
should always be runnable with `nix run`. At present,
the derivation is missing both `meta.mainProgram`
and `pname`– this means that `nix run` falls back
to inferring the bin path from `name`. This is
unreliable and depends on faulty heuristics.
For context, reference the following snippet from
`nix run --help`:
If installable evaluates to a derivation, it will try to execute the
program <out>/bin/<name>, where out is the primary output store path
of the derivation, and name is the first of the following that exists:
· The meta.mainProgram attribute of the derivation.
· The pname attribute of the derivation.
· The name part of the value of the name attribute of the derivation.
Currently all packages defined by a call to runCommand have their
meta.position pointing to trivial-builders.nix.
This change makes uses of runCommand that supply at least one attribute
in the second argument point to the right file.
While searching for something different I wondered why there is a
trivial-builders.nix file next to the trivial-builders directory where
only tests live. Lets fix that.
