Disables IGMP snooping on br-wan
As it causes OpenWRT to drop neighbor announcements on br-wan that are caused by neighbor solicitations for solicitated node link-local addresses (ff02::1:ffxx:xxxx). In turn distrupts the fastd handshake process after some time (e.g. with 24h reconnects), such that fastd will not be able to reestablish a connection via IPv6 (again).
Notice that it becomes necessary to add the ffpb-v6uplink package in site.mk again for this change to be included.
