Bump scaffolding-go, pulling in Go 1.11 (#9)

This unpins our version of core/scaffolding-go which in turn will pull
in the latest version of core/go.

All of A2 builds and passes tests with this change in place:

https://buildkite.com/chef/chef-a2-master-verify/builds/17409

In the past we had pinned our version of Go to avoid this bug:

golang/go#28065

However, rather than pinning, we should track down any places where
that is still an issue and either make sure those builds either have
gcc available or set GCO_ENABLED=0.
