selftests: forwarding: lib: Allow list of IPs for IGMPv3/MLDv2 



The testsuite that checks for mcast_max_groups functionality will need
to generate IGMP and MLD packets with configurable number of (S,G)
addresses. To that end, further extend igmpv3_is_in_get() and
mldv2_is_in_get() to allow a list of IP addresses instead of one
address.
