Tell keystore which SIDs can unlock this user
If biometric unlock is enabled, we tell keystore at lock time so that
a key can be set up in KM which unlocks UNLOCKED_DEVICE_REQUIRED keys
based on auth tokens carrying those SIDs. This also has the effect that
if there is no biometric unlock, UNLOCKED_DEVICE_REQUIRED keys have
full cryptographic protection, per NIAP requirements.
