No functional changes, preparation for utrace-ptrace.
Change ptrace_signal() to check PT_PTRACED instead of task_ptrace() != 0.
Currently this is the same, PT_PTRACED must be always set if the task is
ptraced.
This change is needed to make sure ptrace_sgnal() does nothing if ptrace
is implemented on top of utrace.
