crypto: add crypto tests for single block DES-ECB and DES-CBC
The GNUTLS crypto provider doesn't support DES-ECB, only DES-CBC. We can use the latter to simulate the former, if we encrypt only 1 block (8 bytes) of data at a time, using an all-zeros IV. This is a very inefficient way to use the QCryptoCipher APIs, but since the VNC authentication challenge is only 16 bytes, this is acceptable. No other part of QEMU should be using DES. This test case demonstrates the equivalence of ECB and CBC for the single-block case. Signed-off-by: Daniel P. Berrangé <berrange@redhat.com>
