Avoid passing USER_ALL to getInputMethodBindingController()

This CL fixes a bug that sending ACTION_CLOSE_SYSTEM_DIALOGS to
USER_ALL can register user -1 into IMMS#mUserDataRepository.

The root cause was that

  ImmsBroadcastReceiverForAllUsers#onReceive()

had passed senderUserId as is even when it is USER_ALL (-1).

There must be no observable behavior change in the single-user
mode. As for multi-user mode, InputMethodMenuController{,New} are not
yet supported thus there should be no behavior change.
