On OnePlus Nord CE3 (ziti), shimming `__system_property_get()` is not
enough. Without this change, `vendor.fingerprint.cali` is set to 0 when
`ro.boot.vbmeta.device_state` is unset.
Test: Ensure adb logcat | grep "lcd LockState" does not show up as NULL
Ensure adb shell getprop vendor.fingerprint.cali is 1
