[PATCH net] selftest/net/forwarding: declare NETIFS p9 p10

The resent GRE selftests defined NUM_NETIFS=10. If the users copy
forwarding.config.sample to forwarding.config directly, they will get
error "Command line is not complete" when run the GRE tests, because
create_netif_veth() failed with no interface name defined.

Fix it by extending the NETIFS with p9 and p10.
