Bring in JHB's cryptocheck tool

It can be used to validate basic algorithm correctness on a variety of inputs,
by comarison to openssl.

While here, add some sanity to the crypto/Makefile.

The tool may not be perfect, but getting it in tree where collaboration can
happen is a nice first step.  The pace of development outside of svn seems
to have slowed down mid-2017.
