vgo: fix Go 1.9 check

What matters is the GOROOT source tree we are using,
not the version of Go that built the vgo binary.
Also the old version check was too late: vgo would have
already failed due to having the wrong source tree.

Fixes golang/go#24694.

Versioned Go Prototype (vgo)

This repository holds a prototype of what the go command might look like with integrated support for package versioning.

See research.swtch.com/vgo for documents about the design.

Download/Install

Use go get -u golang.org/x/vgo.

You can also manually git clone the repository to $GOPATH/src/golang.org/x/vgo.

Report Issues / Send Patches

See CONTRIBUTING.md.

This is still a very early prototype. You are likely to run into bugs. Please file bugs in the main Go issue tracker, golang.org/issue, and put the prefix x/vgo: in the issue title.

Thank you.
