Better logging for ethernet related petting.

recover_duts ethernet hook periodically pets the connection of lab machine to
guarantee connectivity or force a reboot.  This change adds logging to
/var/log/messages in the event this petting fails.

Change also quiets the ping output to only print the summary info.
