T5165: Implement policy local-route source and destination port

Add `policy local-route` source and destination port

set policy local-route rule 23 destination port '222'
set policy local-route rule 23 protocol 'tcp'
set policy local-route rule 23 set table '123'
set policy local-route rule 23 source port '8888'

% ip rule show prio 23
23:	from all ipproto tcp sport 8888 dport 222 lookup 123
