iprule: Insert network and address ip rules before main table lookup rule

Specific IP address and network rules are now checked before the main table lookup as the main table
often holds a default route. As a result the IP address and network rules pointing to a specific
routing table will not be checked anymore; by reversing the order the specific routing tables
are checked first if the ip rule matches.
