X.509: Support parsing certificate using SM2 algorithm
The SM2-with-SM3 certificate generated by latest openssl no longer reuses the OID_id_ecPublicKey, but directly uses OID_sm2. This patch supports this type of x509 certificate parsing. Signed-off-by: Tianjia Zhang <tianjia.zhang@linux.alibaba.com> Signed-off-by: Jarkko Sakkinen <jarkko@kernel.org>
