Reworked biometric weak check functions

Renamed isBiometricEnabled to isBiometricWeakInstalled.  This function
now checks if the system property is set, the facelock package is
installed, and if the phone has a front facing camera.  It no longer
checks if facelock is currently set as the unlock method.
Added isBiometricWeakInstalled checks to all cases where facelock is used
in LockPatternKeyguardView
