go/analysis/unitchecker: add erroras analysis to align with go vet

Add `erroras` analysis to the `unitchecker` example that mimics go vet.

The unitchecker according to its comments is an example of replicating
the analysis performed by go vet using the unitchecker. The example is
missing the erroras analysis that was added to go vet in
golang/go@9f76566. This change brings the example back inline with the
analysis performed by go vet.

Close golang/go#35486

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.
