Force a reprovisioning on device renewal

[ Merge of http://go/wvgerrit/169374 ]

Device renewals used to require that OEMs remove provisioning
certificates as part of the OTA update process. Instead, a change
in system ID is relied upon to indicate a change in root of trust.
If a change in System ID is detected, reprovisioning will be forced.

This is not enabled for ATSC devices or L3 devices. For the latter a
change in system ID may occurs without a change in RoT.
