    Core: Use ro.build.date to signal mIsUpgrade

    M: We use a static fingerprint that is only changed when a new OEM build is released, so
       every flash shows Android is starting instead of upgrading.  This will fix that.
    N: even though we dont have the dexopt sceen on N, this is still needed to delete the
       correct caches, and grant/deny specific runtime permissions like a true oem update
       would do.

    fw/b UserManagerService: Use ro.build.date to signal upgrades

    *) We changed PackageManagerService to use Build.DATE instead of
       Build.FINGERPRINT to detect upgrade.  Do the same for
       UserManagerService.
    *) Affects generation of preboot intent and app data migration.
