raven: include factory/shipping UDFPS based on target

This CL transitions the regular build to the AIDL fingerprint HAL, while
keeping the factory build on HIDL.

AuthService reports "Registering HIDL ID: 0 Modality: 2 Strength: 15"
only for the factory build.

Bug: 188193467
Test: build raven-userdebug
Test: build factory_raven-userdebug
Test: adb logcat | grep AuthService
