Use InstallRootKeyCertificate for keybox and cert

Browse Source 
Merge from Widevine repo of http://go/wvgerrit/55461

This CL allows provisioning 3.0 devices to install their OEM certs
from an initialization partition.  This method is already used for
keyboxes on Android -- we are just adding the ability to use it for
OEM certs, also.

Also, for v15, we require OEMCrypto to report a valid certificate in
the unit tests.
