selftests: hsr: Check duplicates on HSR with VLAN
Previously the hsr_ping test only checked that all nodes in a VLAN are reachable (using do_ping). Update the test to also check that there is no packet loss and no duplicate packets by running the same tests for VLANs as without VLANs (including using do_ping_long). This also adds tests for IPv6 over VLAN. To unify the test code, the topology without VLANs now uses IP addresses from dead:beef:0::/64 to align with the 100.64.0.0/24 range for IPv4. Error messages are updated across the board to make it easier to find what actually failed. Also update the VLAN test to only run in VLAN 2, as there is no need to check if ping really works with VLAN IDs 2, 3, 4, and 5. This lowers the number of long ping tests on VLANs to keep the overall test runtime in bounds. It's still necessary to bump the test timeout a bit, though: a ping long tests takes 1sec, do_ping_tests performs 12 of them, do_link_problem_tests 6, and the VLAN tests again 12. With some buffer for setup and waiting and for two protocol versions, 90sec timeout seems reasonable.
