Allow skipping timestamp check in certain debug conditionsq10.0
As proposed in go/ota-downgrade, the android auto team wants to install
a full OTA with the older timestamp. We will only allow it on devices
with userdebug build, and has the property "ro.ota.allow_downgrade"
set. Data wipe is almost inevitable due to the probability of security
patch level and database rollback.
Test: set the property and install a full payload with older timestamp.
