LSM: Remove unused arguments from security_path_truncate().
When commit be6d3e56a6b9b3a4ee44a0685e39e595073c6f0d "introduce new LSM hooks
where vfsmount is available." was proposed, regarding security_path_truncate(),
only "struct file *" argument (which AppArmor wanted to use) was removed.
But length and time_attrs arguments are not used by TOMOYO nor AppArmor.
Thus, let's remove these arguments.
