make build failed in folder docker

Nobody has claimed this yet.

Hi all,

When I tried to build the docker image, I got the following error:
```

```

It seems that the go build failure occurs in the docker and the `GOPATH` and `GOROOT` are set in the `Dockerfile.build.ubuntu`
https://github.com/mandiant/gocrack/blob/bd430693ffc31a60be3258acc8f523d9e9e65510/docker/Dockerfile.build.ubuntu#L72-L73
Is there any problem in the `Dockerfile.build.ubuntu`?

Thank you!

Start with docker/Dockerfile.build.ubuntu around lines 72–73 and the build target in Makefile. Reproduce `make build` in the Docker environment, then inspect how the missing Go packages are expected to be provided; done means the Docker build completes without the reported dependency errors.
