Add test for VLAN ping for HSR. The test adds vlan interfaces to the hsr
interface and then verifies if ping to them works.

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.

Fixed MAC addresses help with debugging as last four bytes identify the
network namespace.
Moreover, it allows to mimic the real life setup with for example bridge
having the same MAC address on each port.

The hsr_ping test reports the following errors:

INFO: Initial validation ping.
INFO: Longer ping test.
INFO: Cutting one link.
INFO: Delay the link and drop a few packages.
INFO: All good.

That is because the cleanup code for the 2nd round test before
"setup_hsr_interfaces 1" is removed incorrectly in commit 680fda4f6714
("test: hsr: Remove script code already implemented in lib.sh").
This patch fixes it by re-setup the namespaces using
setup_ns ns1 ns2 ns3
command before "setup_hsr_interfaces 1". It deletes previous namespaces
and create new ones.

After this change the single SAN device (ns3eth1) is now replaced with
two SAN devices - respectively ns4eth1 and ns5eth1.
It is possible to extend this script to have more SAN devices connected
by adding them to ns3br1 bridge.

Current code checks if ping command output match hardcoded pattern:
"10 packets transmitted, 10 received, 0% packet loss,".
Such approach will work only from one ping program version (for which
this test has been originally written).
This patch address problem when ping with different summary output
like "10 packets transmitted, 10 packets received, 0% packet" is
used to run this test - for example one from busybox (as the test
system runs in QEMU with rootfs created with buildroot).
The fix is to modify output of ping command to be agnostic to ping
version used on the platform.

Move the code and group into functions so it will be easier to extend
the test to HSRv1 so that both versions are covered.
Move the ping/test part into do_complete_ping_test() and the interface
setup into setup_hsr_interfaces().

The timeout in the while loop is never subtracted due wrong usage of
`let' leading to an endless loop if the former condition never gets
true.
Put the statement for let in quotes so it is parsed as a single
statement.

This test adds a basic HSRv0 network with 3 nodes. In its current shape
it sends and forwards packets, announcements and so merges nodes based
on MAC A/B information.
It is able to detect duplicate packets and packetloss should any occur.
