openssl: import fixes from upstream

Import the following two commits from upstream:

  commit 72126d6c8b88abd69c3565fc3bbbd5ed1e401611

      pkey: check existence of EVP_PKEY_get0()

      EVP_PKEY_get0() did not exist in early OpenSSL 0.9.8 series. So define
      ourselves if needed.

      test/test_cipher: fix test with OpenSSL 1.0.1 before 1.0.1d

      Set the authentication tag before the AAD when decrypting.

      Before OpenSSL commit 96f7fafa2431 ("Don't require tag before ciphertext
      in AESGCM mode", 2012-10-16, at OpenSSL_1_0_1-stable branch, included in
      OpenSSL 1.0.1d), the authentication tag must be set before any calls of
      EVP_CipherUpdate().

They should fix build on CentOS 5 and Ubuntu 12.04 respectively.
