a1a4809abf tpm2: CryptSym: fix AES output IV
The TPM is supposed to provide the output IV in the ivInOut parameter in
CryptSymmetricEncrypt. In the case of using the openssl routines, the
output IV is missed, and the resulting output from the TPM is in the
input IV.

OpenSSL unfortunately does not export EVP_CIPHER_CTX_iv() until
tags/OpenSSL_1_1_0, so we have to fall back to the reference code for
previous OpenSSL versions.

Fixes: CVE-2021-3446
