tests: crypto: add cipher speed benchmark support
Now we have two qcrypto backends, libiary-backend and afalg-backend, but which one is faster? This patch add a cipher speed benchmark, it helps us to measure the performance by using "make check-speed" or using "./tests/benchmark-crypto-cipher" directly.
