ipv4: adjust version tags in @ipv4_routing_rules_manipulation test
The change was done in 1.41.4+ ([1]) and backported to 1.40.3+ ([2]). Thus the proper tags are as such.
Also, when a test is guared by @ver+=X, then the older version should have exactly(!) @ver-X, and not come up with different version tags. That is, because we want that there is no overlap and no gap between the version for which the test is enabled.
