These tests were introduced in #44271, where we migrated the Ginkgo test into BPF unit test. However, as noted in the PR comments, the Ginkgo tests were mainly testing the East/West scenario rather than the North/South. This commits renames then the introduced tests to north/south, and refactors a bit their infra to accommodate for east/west tests introduced in the follow-up commit.

This commit introduces East/West tests for both IPv4 and IPv6 fragments in the tc_nodeport_lb test suite. They specifically make sure that when ENABLE_PER_PACKET_LB is enabled, the load balancer correctly handles fragments from bpf_lxc. These tests are complementary of the previous commit, where we refactored the North/South tests for this codepath (netdev). Signed-off-by: Simone Magnani <simone.magnani@isovalent.com>

In #44271, we moved the Ginkgo tests into BPF unit tests.
However, we tested only the North/South path (netdev).
This PR adds the East/West LB case when ENABLE_PER_PACKET_LB is defined (bpf_lxc).
