Subject: [PATCH] crypto: Fix aead_test build on aarch64

aarch64 does not allow allignments larger than 16 bytes.

Before this change, `aead_test.cc` build on aarch64 was failing with the
following errors:

aead_test.cc:543:54: error: requested alignment 64 is larger than 16 [-Werror=attributes]
   alignas(64) uint8_t key[EVP_AEAD_MAX_KEY_LENGTH + 1];
aead_test.cc:544:58: error: requested alignment 64 is larger than 16 [-Werror=attributes]
   alignas(64) uint8_t nonce[EVP_AEAD_MAX_NONCE_LENGTH + 1];
aead_test.cc:545:39: error: requested alignment 64 is larger than 16 [-Werror=attributes]
   alignas(64) uint8_t plaintext[32 + 1];
aead_test.cc:546:32: error: requested alignment 64 is larger than 16 [-Werror=attributes]
   alignas(64) uint8_t ad[32 + 1];
aead_test.cc:564:75: error: requested alignment 64 is larger than 16 [-Werror=attributes]
   alignas(64) uint8_t ciphertext[sizeof(plaintext) + EVP_AEAD_MAX_OVERHEAD];
aead_test.cc:572:45: error: requested alignment 64 is larger than 16 [-Werror=attributes]
   alignas(64) uint8_t out[sizeof(ciphertext)];
aead_test.cc:586:50: error: requested alignment 64 is larger than 16 [-Werror=attributes]
   alignas(64) uint8_t key[EVP_AEAD_MAX_KEY_LENGTH];
                                                  ^
