shift "ptrace implies WUNTRACED" from ptrace_do_wait() to wait_task_stopped()

No functional changes, preparation for the next patch.

ptrace_do_wait() adds WUNTRACED to options for wait_task_stopped() which
should always accept the stopped tracee, even if do_wait() was called
without WUNTRACED.

Change wait_task_stopped() to check "ptrace || WUNTRACED" instead.  This
makes the code more explicit, and "int options" argument becomes const in
do_wait() pathes.
