Pyrit computes pairwise master keys (PMKs) to attack WPA/WPA2-PSK. This
test verifies two aspects:

 - Computation of the second round of a HMAC (using SHA-1).
 - A calculation of the PMK key.

Both tests use test vectors from IEEE 802.11-2012, pre-processed to fit
in the model used by Pyrit (one part is pre-calculated before passing it
to the kernel).

The results have been verified with POCL and r600g (mesa master+llvm
trunk).
