cmd/tailscale: exit loop when timeout and pingArgs.num are met

Browse Source 
Currently if you use '-c' and ping a host that times out, ping will
continue running indefinitely. This change exits the loop with "no
reply" when we time out, hit the value specified by '-c' and do not
have anyPong. If we have anyPong it returns nil.
