ptrace: do not use task->ptrace directly in core kernel

No functional changes.

- Nobody except ptrace.c & co should use ptrace flags directly, we have
  task_ptrace() for that.

- No need to specially check PT_PTRACED, we must not have other PT_ bits
  set without PT_PTRACED. And no need to know this flag exists.
