        src/tests/lib/libc/sys: t_ptrace_wait.c

Log Message:
Add a new ATF ptrace(2) test: child_attach_to_its_stopped_parent

Reuse the body of child_attach_to_its_parent for a test attaching to a
stopped parent.

As a workaround to ATF framework (atf-run), run this test in a subprocess.
The raise(SIGSTOP) call breaks the pipe from atf-run, that is polling
whether a process is in order.
According to code inspection the poll(2) call in safe_poll() receives
EINTR and this tears down the test.

This test passes.
