Bump x/tools

I think this might fix #24. I was hitting it while trying go-callvis -focus cuelang.org/go/cue/cmd ./cmd/cue and getting

I tracked down golang/go#25090 to the reported fix in golang/go#45735, so figured bumping the dependency was in order, and lo and behold my panic is gone 🎉

Thank you!

Just as a note: I'm asuming a new release tag hasn't been added. I hit this by using go install with @latest, and resolved by using @master.
