go/vcs: reject update of VCS inside VCS

Manually apply same change as CL 68110 did for cmd/go/internal/get,
but for golang.org/x/tools/go/vcs, to help keep them in sync.

Updates golang/go#22125.
Helps golang/go#11490.

Go Tools

This subrepository holds the source for various packages and tools that support the Go programming language.

Some of the tools, godoc and vet for example, are included in binary Go distributions.

Others, including the Go guru and the test coverage tool, can be fetched with go get.

Packages include a type-checker for Go and an implementation of the Static Single Assignment form (SSA) representation for Go programs.

Download/Install

The easiest way to install is to run go get -u golang.org/x/tools/.... You can also manually git clone the repository to $GOPATH/src/golang.org/x/tools.
