cmd/go/internal/modcmd: add mod -graph

mod -graph dumps the requirement graph in text form,
for processing by other tools. For example, I wondered
why github.com/moby/buildkit was exploring a very
old version of Kubernetes:

    $ vgo mod -graph |
      digraph somepath github.com/moby/buildkit \
          k8s.io/kubernetes@v0.0.0-20150821172800-a412f6a67e3a
