CBC and aes-128 are supported by all of our backends (as far as I can tell), so use aes-128-cbc in our iotests. (We could also use e.g. aes-256-cbc, but the different key sizes would lead to different key slot offsets and so change the reference output more, which is why I went with aes-128.)

We could taylor the algorithm list to what gnutls supports, but this is a test that is run rather rarely anyway (because it requires password-less sudo), and so it seems better and easier to skip it. When this test is intentionally run to check LUKS compatibility, it seems better not to limit the algorithms but keep the list extensive.
