[test] enhance test-008-multicast-traffic.py (#12816)

Browse Source 
This commit updates `test-008-multicast-traffic.py` to use a strict
equality check for the number of multicast `ping` responses when the
ping originates from an SED.

The test now also verifies the `RxSuccess` IP counter on the SED to
ensure it increases by exactly the number of expected replies. This
confirms that the parent correctly avoids forwarding the original
multicast echo request back to the originating SED, even if the SED
is subscribed to the multicast address. This validates the behavior
introduced in PR #12329.
