Subject: firewall: T5814: Retain legacy 'accept' behaviour and re-order
 migration

Pre-1.4 firewall 'accept' action acted as a 'return'. This change ensures the migrated rules meet the expected behaviour.

This commit also re-orders migrated in/out/local jumps ordered by direction instead of interface.
