go.tools/cmd/vet: fix go.tools build 

TBR: gri

I cannot create an issue on the tracker for some reason, so here it is:
go vet contains this snippet:

        if types.IsAssignableTo(typ, errorType) || types.IsAssignableTo(typ, stringerType) {

It's getting the wrong answer: It claims

interface {
        f()
}

or even

interface {
        f() float64
}

matches the Error and Stringer interfaces. Both of them.  This causes a test failure:
$ go test code.google.com/p/go.tools/cmd/vet
BUG: errchk: testdata/print.go:124: missing expected error: '"for printf verb %s of wrong type"'
$
This worked until very recently.
