Remove more dead code from KeyguardUpdateMonitor

Browse Source 
1. DisplayClientState is not used anywhere.
2. mUserFaceUnlockRunning is never updated because
   com.android.facelock.FACE_UNLOCK_STARTED/STOPPED
   intents are used/started anywhere. This seems to be
   code untouched for a long time.

Test: atest KeyguardUpdateMonitorTest passes
