fmt: print byte stringers correctly

type T byte
func (T) String() string { return "X" }

fmt.Sprintf("%s", []T{97, 98, 99, 100}) == "abcd"
fmt.Sprintf("%x", []T{97, 98, 99, 100}) == "61626364"
fmt.Sprintf("%v", []T{97, 98, 99, 100}) == "[X X X X]"

This change makes the last case print correctly.
Before, it would have been "[97 98 99 100]".

Fixes #8360.
