example/ivy: add a "// +build" comment in tools.go

The modules in x/mobile are still tested under Go 1.16, which emits a
vet warning for files that have "//go:build" constraint comments
without matching "// +build" comments.

This fixes a build failure observed on the Go dashboard:

Go support for Mobile devices

Go Reference

The Go mobile repository holds packages and build tools for using Go on mobile platforms.

Package documentation as a starting point:

Caution image

The Go Mobile project is experimental. Use this at your own risk. While we are working hard to improve it, neither Google nor the Go team can provide end-user support.

This is early work and installing the build system requires Go 1.5. Follow the instructions on golang.org/wiki/Mobile to install the gomobile command, build the basic and the bind example apps.
