Build: Migrate middleware-mockserver to modern JS
The `test/middleware-mockserver.js` file used to have the same ESLint
settings applied as other test files that are directly run in tested
browsers. Now it shares settings of other Node.js files.

The file is now also written using modern JS, leveraging ES2018.

Closes gh-5196
