Update private space animation timings

The entire animation is 800ms where there are differences between lock/unlock.
Unlock 1.0:
   app Opacity: time = 400 -> 800ms Linear
   text opacity: time = 500 -> 800ms Linear
   settingsAndLockGroup "size": time = 400 -> 800ms Standard
   settingsGear: time = 400 -> 800ms Linear
Lock 2.0:
   app Opacity: time = 0 -> 400ms Linear
   text opacity: time = 0 -> 50ms Linear
   settingsAndLockGroup "size": time = 0 -> 400ms Standard
   settingsGear: time = 0 -> 400 Linear
