delete/update deprecated java cryptography links (#201)

Google Keyczar: Deprecated, developers recommend Tink
Google Tink: The Tink project repository will be archived soon since it has been split into multiple GitHub repositories for different programming languages. The link is replaced with the new java Tink repository link.
keywhiz: Deprecated and no longer maintained
