PolicyVersionUpgrader: fix ERROR + stacktrace on first boot
On first boot it is expected that the device_policies_version file
doesn't exist yet, so properly handle this case.
Bug: 280155081
Test: Booted Cuttlefish and verified that logcat no longer contains
"DevicePolicyManager: Error reading version" and the stacktrace,
but does contain "DevicePolicyManager: Upgrading from version 0"
