Update swipe up from the locked shade behavior

Browse Source 
If the device has UDFPS enrolled, swiping up from
the locked shade on keyguard brings the user back to
the lock screen instead of showing the bouncer. We
do this because the lock screen still has the UDFPS
affordance for device entry. Users can additionally
swipe up again if they want to use the input bouncer
for device entry.
