Disk encryption keys are derived using scrypt. If available, this is
done by means of keymaster. An RSA key is generated and password is
signed by that key. The signature is used as the key.
With the hidlization of the keymaster HAL, this code had to be ported.
This test checks the equivalence of the legacy implementation with
the new hildized one.
