On signal reception, return EAI_SYSTEM from openvpn_getaddrinfo().
A signal (except SIGUSR1) received while waiting for getaddrinfo() is
considered fatal, so openvpn_getaddrinfo() is destroying the returned
information with freeaddrinfo(), but still signalled "success" (0)
to the caller - so if the caller accessed *res before checking
*signal_received, it would access just-free()ed memory, which on some
platforms still worked and on others caused a crash.
Also, ensure that *ai is also NULLed in the caller now.
