Fix BiometricPrompt for face + non-UDFPS fingerprint

Currently, the dual-sensor config for BiometricPrompt requires a face
sensor and under-display fingerprint sensor. This commit loosens the
restriction to also accept non-UDFPS fingerprint sensors. The fallback
logic in this case is the same as for face + UDFPS.

Test: Manually verified that BiometricPrompt no longer crashes
