Supress IKeygaurdSerivce#setOccluded binder call from WM.

When remote animation is enabled for keygaurd (un)occluded status update,
KeyguardServices recieves binder call via IRemoteAnimationRunner interface
when occlusion status chagnes.

The only place we need to keep IKeygaurdSerivce#setOccluded call is
in ServiceConnection#onServiceConnected. This is used to synchronize
keyguard occluded status in WM and SysUI process when SysUI process
restarts, which is handled without any animation.
