Run the packet loss and reordering tests also for both HSR versions. Now
they can be removed from the hsr_ping tests completely. The timeout needs
to be increased because there are 15 link fault test cases now, with each
of them taking 5-6sec for the test and at most 5sec for the HSR node tables
to get merged and we also want some room to make the test runs stable.

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.

The HSR test, hsr_ping.sh, actually needs 7 min to run. Around 375s to
be exact, and even more on a debug kernel or kernel with other network
security limits. The timeout setting for the kselftest is currently 45
seconds, which is way too short to integrate hsr tests to run_kselftest
infrastructure. However, timeout of hundreds of seconds is quite a long
time, especially in a CI/CD environment. It seems that we need
accelerate the test and balance with timeout setting.
The most time-consuming func is do_ping_long, where ping command sends
10 packages to the given address. The default interval between two ping
packages is 1s according to the ping Mannual. There isn't any operation
between pings thus we could pass -i 0.1 to ping to make it 10 times
faster.
While even with this short interval, the test still need about 46.4
seconds to finish because of the two HSR interfaces, each of which is
tested by calling do_ping func 12 times and do_ping_long func 19 times
and sleep for 3s.
So, an explicit setting is also needed to slightly increase the
timeout. And to leave us some slack, use 50 as default timeout.
