Unit Test Updates for v13

Merge from widevine of http://go/wvgerrit/23042

This updates unit tests to account for key control block changes for
OEMCrypto v13.  There are two new bits, restricting SRM version and
restricting analog output.  The verification string is also updated.

Part of this is to include some simple unit tests for the SRM
functions.
