tests: crypto: add hmac speed benchmark support
This patch add a hmac speed benchmark, it helps us to measure the performance by using "make check-speed" or using "./tests/benchmark-crypto-hmac" directly. Signed-off-by: Longpeng(Mike) <longpeng2@huawei.com> Signed-off-by: Daniel P. Berrange <berrange@redhat.com>
