Cygwin: always add sigmask to child info
Even after fork, we might need the parent sigmask without having
access to the real _main_tls. There's a short time at process startup,
when _main_tls points to the system-allocated stack, but wait_sig is
already running. If we can't lock _main_tls, because find_tls can't
find it yet, we now access the parent's sigmask via child_info.
