gprs: ping.py: Disable ipv6 ctx activate test

osmo-ggsn is failing to create tun ipv6 device in Prod main unit.
Afterwards, as the iface is not created, it cannot find its link-local
ip and it doesn't configure the ipv6 pool. Later on, when an ipv4v6 ctx
is requested, it fails because apn doesn't support ipv6 (because the
pool is not created).
