CM script update_route grep whole word
CM script update_route grep whole word

Currently, when looking into the default_route file, it's trying
to grep either "inet" or "inet6" but we aren't doing
whole word grep, so "inet" is catching inet6 results as well.
Therefore, added a "-w". Also check both protocols when saving the
previous default route, for instance when ethernet is using IPv4,
but our cellular uses IPv6.
