Yueh-Shun Li 79a1e9d729 tests.trivial-builders.references: refactor expression
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.
