 A single fix for posix CPU timers
 
   When a thread is cloned, the posix CPU timers are not inherited.
 
   If the parent has a CPU timer armed the corresponding tick dependency in
   the tasks tick_dep_mask is set and copied to the new thread, which means
   the new thread and all decendants will prevent the system to go into full
   NOHZ operation.
 
   Clear the tick dependency mask in copy_process() to fix this.
