test: improve the code in test-pipe.js
* use const and let instead of var * use common.mustCall to control functions executions * use assert.strictEqual instead of assert.equal * use assert.ifError to handle errors * use arrow functions * remove console.log and process.stdout.write PR-URL: #10452 Reviewed-By: James M Snell <[email protected]> Reviewed-By: Luigi Pinca <[email protected]> Reviewed-By: Brian White <[email protected]>
