docker/go/nethttp: go build -mod=mod (#1061) (#1067)

Go 1.16 changed the "go build" command so that it no longer automatically updates go.mod and go.sum. Because we dynamically change the Go agent version, we cannot set go.mod and go.sum ahead of time. Pass in `-mod=mod` to reinstate the old behaviour. Co-authored-by: Andrew Wilkins <[email protected]>
