s390: move cputime accounting fields from thread_info to thread_struct

Browse Source 
The user_timer and system_timer fields are used for the per-thread
cputime accounting code. The access to these values is simpler if
they are moved to the thread_struct as the task_thread_info(tsk)
indirection is not needed anymore.
