router: skip parse_routes when ra_default > 1
It does not make sense to scan the entire routing table if the decision
will be overridden afterwards.
This makes it possible to use odhcpd on a router with full IPv6 BGP
table, by setting ra_default to 2. Without this change, odhcpd is
constantly busy reading /proc/net/ipv6_route, and doesn't respond to
router solicitations in time.
