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.

standard build; make it use only static libraries as per documented
limitations of APCT.

The libcrypto and libssl modules (and their respective static and host
versions) use LOCAL_EXPORT_C_INCLUDE_DIRS thus just including the module
is sufficient.
Additionally, cryptfs.h was including an OpenSSL header just to get the
length of a SHA-256 hash. Rather than force all users of this header to
also depend on libcrypto, it's easier just to define that value in the
header file.
