build/constraint: update doc to mention a feature added in Go 1.17

The pkg documentation mentions that the "//go:build" syntax "will be"
added in Go 1.17. In fact, it has been added in that Go release, so the
documentation can now be updated.

// Package constraint implements parsing and evaluation of build constraint lines.
// See https://golang.org/cmd/go/#hdr-Build_constraints for documentation about build constraints themselves.
//
// This package parses both the original “// +build” syntax and the “//go:build” syntax that will be added in Go 1.17.
// The parser is being included in Go 1.16 to allow tools that need to process Go 1.17 source code
// to still be built against the Go 1.16 release.
// This package parses both the original “// +build” syntax and the “//go:build” syntax that was added in Go 1.17.
// See https://golang.org/design/draft-gobuild for details about the “//go:build” syntax.
