argon2: add missing amd64 tags
The change fixes argon2_test build failure which currently
reads as follows when built with gccgo:
./argon2/blamka_ref.go:9:1: error: redefinition of 'processBlock'
func processBlock(out, in1, in2 *block) {
^
./argon2/blamka_amd64.go:53:1: note: previous definition of 'processBlock' was here
func processBlock(out, in1, in2 *block) {
^
./argon2/blamka_ref.go:13:1: error: redefinition of 'processBlockXOR'
func processBlockXOR(out, in1, in2 *block) {
^
./argon2/blamka_amd64.go:57:1: note: previous definition of 'processBlockXOR' was here
func processBlockXOR(out, in1, in2 *block) {
^
