Add simple tests for the CPACF instructions implemented:
- kdsa - minimal as only query is implemented
- kimd - query, sha256, sha512
- klmd - query, sha256, sha512
- km - query, aes 128, 192, 256 with clear and prot key
- kmac - minimal as only query is implemented
- kmc - query, aes 128, 192, 256 with clear and prot key
- kmctr - query, aes 128, 192, 256 with clear and prot key
- pcc - query, xts aes 128, 256 and prot key xts aes 128, 256
- prno - query, trng
No test for pckmo as this is a privileged instruction.
No test for kma, kmf, kmo as these instructions are currently
not implemented at all.

I get failures when running these on a real z17, for example:
$ ./cpacf-kdsa
test_kdsa_query failed
cpacf-kdsa: 1 failures
Ok, I only tested on qemu. But of course you are right, it should
work fine on a real machine also. Will check this ...
Oh maybe one thing: query works with a fixed bitfield of subfunctions
which are supported - by the QEMU CPACF implementation. So a real
query may result in a lot of more subfunctions enabled in the result
bitfield and thus the compare will fail.
