Return null system ID for built-in DRM cert devices.

Browse Source 
[ Merge of http://go/wvgerrit/153489 ]

OEMCrypto does not provide an API for retrieving the system ID when
the TEE uses a built-in DRM certificate (provisioning 1.0).  New OEMs
and Android devices do not use prov 1.0; however, the Zimperium CDM
(at least the tests) use a built-in certificate and are failing
certain tests because of the missing system ID.  To address this
failure; the CDM SystemIdExtractor has been updated to return a null
system ID.

Bug: 235879962
Test: system_id_extractor_unittest
