Expect SIGSTOP in attach3 in t_ptrace_wait{,3,4,6,id,pid} 

Set SIGSTOP as expected signal in attach3, is it is preferred in general.
Not just because FreeBSD and Linux work this way, but to make it consistent
and regardless of relation between tracee and tracer always get the same
signal.

attach3 tests parent attaching with PT_ATTACH to its child
