cmd/gomobile: create go.sum at the temporary directory

As of Go1.16, `go build` fails if go.sum does not exist. This change
fixes this issue by forcing to create go.sum by calling `go mod tidy`.

Closes golang/go#44162

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.
