kuntao: Implement fingerprint gestures as KeyDisabler

 * fingeprint gestures can be enabled by calling jni function from
 libvcfp.so. It has to be loaded into com.synaptics.fingerprint.Fingerprint
 class
 * added minimal needed synaptics Fingerprint and FingerprintCore classes
 * added dummy classes that presense checked on jni library init
   com/synaptics/fingerprint/CapturedImageData
   com/synaptics/fingerprint/DeviceInfo
   com/synaptics/fingerprint/EnrollProgress
   com/synaptics/fingerprint/EnrollResult
   com/synaptics/fingerprint/FingerprintEvent
   com/synaptics/fingerprint/IdentifyResult
   com/synaptics/fingerprint/NavigationReport
   com/synaptics/fingerprint/NavigationEvent
 * added libvcfp.so to proprietary-files.txt
 * adjusted init files and overlay to enable KeyDisabler
 * added keylayot for single touch (keycode 562) and long touch (keycode 563)
