tests: Use ping timeout instead of deadline.

Many system tests currently use ping with the combination of a low packet count (-c 3), short interval between sends (-i 0.3) and a _deadline_ of 2 seconds (-d 2). This combination of options may lead to a situation where more than count packets are sent however ping will stop when count packets are received. This results in a failed test due to how the result is checked, for example: ping6 -q -c 3 -i 0.3 -w 2 fc00::3 | FORMAT_PING @@ -1,2 +1,2 @@ -3 packets transmitted, 3 received, 0% packet loss, time 0ms +4 packets transmitted, 3 received, 25% packet loss, time 0ms To reiterate, in the above example there is no packet loss, but ping stops after _receiving_ 3 packets, not bothering with waiting for the response to the fourth packet it just sent out. If we look at the iputils ping manual for the -w deadline option we can read that this is expected behavior: > Specify a timeout, in seconds, before ping exits regardless of > how many packets have been sent or received. In this case ping > does not stop after count packet are sent, it waits either for > deadline expire or until count probes are answered or for some > error notification from network. To avoid these kinds of failures in checks where a response is expected, we replace ping -w with ping -W. We keep ping -w for checks where it is expected to NOT get a response.
