selftests: net: add missing config for amt.sh

[ Upstream commit c499fe96d3f75a5cf50de6089dd8f1cddd1301a9 ]

Test needs IPv6 multicast. smcroute currently crashes when trying
to install a route in a kernel without IPv6 multicast.

Fixes: c08e8baea78e ("selftests: add amt interface selftest script")
