cmd/godoc: update findGOROOT

After godoc stopped being part of the Go distribution, the location
of the godoc binary and the go binary can be different. Hence the old
GOROOT finding logic does not work anymore.

We shell out to "go env GOROOT" to return the new GOROOT.

Fixes golang/go#23445

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.
