strconv: quote rune 007F as \x7f, not \u007f
\u007f is not wrong but it's weird to use \u when we could use the shorter \x. Fixes #52062 Change-Id: Ica4bdc2463128051876f44e15297ed1e9edf1de8 Reviewed-on: https://go-review.googlesource.com/c/go/+/397255 Trust: Ian Lance Taylor <iant@golang.org> Reviewed-by: Rob Pike <r@golang.org>
