test: refactor test-net-server-bind

* Use common.mustNotCall() and common.mustCall() as appropriate
* Use block scoping
* Move assertions out of `exit` handler and into callbacks
* Order assert.strictEqual() args per docs
* Remove console.log() calls
* Move test from `parallel` to `sequential` so `common.PORT` can be used
  without conflicting with OS-provided ports in other `parallel` tests
