Add unit test to verify signature

Browse Source 
Merge from widevine repo of http://go/wvgerrit/21521

On devices that use provisioning 3.0, the function
OEMCrypto_GenerateSignature will only be used for a license renewal.
This CL adds a call to OEMCrypto_GenerateSignature to the refresh key
tests.  Otherwise, there would be no coverage at all for that
function.
