Include the biometricEnabled state in the fingerprintEnabled state

This fixes an issue where the sideFps alternate bouncer was showing
even when biometrics weren't enabled in settings for device entry.

Test: manually disable biometrics for phone unlock in Security
settings, enroll sideFPS and see that tapping on an affordance
on the lockscreen will not show the alternate bouncer
Test: atest BiometricSettingsRepositoryTest
Flag: NONE
