[Toybox] [PATCH] ping: fix -q behavior.

[enh]

the networking folks said it probably doesn't matter. they did point
out that it's a lot easier to implement the toybox behavior with the
iputils ping than vice versa.

they said they'd be much more worried about whether we use IP_RECVERR
and parse ICMP errors correctly, or do link-local ping correctly...
