x/mod: apply go fix and go vet

(Needed so that I can vendor this into std,
a consequence of vendoring x/tools into std.)

A number of places were further simplified by hand.

PkgGoDev

This repository holds packages for writing tools that work directly with Go module mechanics. That is, it is for direct manipulation of Go modules themselves.

It is NOT about supporting general development tools that need to do things like load packages in module mode. That use case, where modules are incidental rather than the focus, should remain in x/tools, specifically x/tools/go/packages.

The specific case of loading packages should still be done by invoking the go command, which remains the single point of truth for package loading algorithms.
