iptables: Test if match and target arguments are also the same

iptables: Test if match and target arguments are also the same

We need to verify that also the arguments are the same, e.g.
if we have two rules like

-t filter -A INPUT -m mark --mark 1 -j LOG
-t filter -A INPUT -m mark --mark 2 -j LOG

then the matcher and the target would be the same without looking
at '1' or '2'.

When deleting a rule, we would always remove the first
rule which matches the 'match' type and target type, so let's have a
look also on the arguments. iptables does it the same way.
