[PATCH net v2 09/17] selftests: forwarding: hw_stats_l3_gre: Skip when using veth pairs

Layer 3 hardware stats cannot be used when the underlying interfaces are
veth pairs, resulting in failures:

# ./hw_stats_l3_gre.sh
TEST: ping gre flat [ OK ]
TEST: Test rx packets: [FAIL]
Traffic not reflected in the counter: 0 -> 0
TEST: Test tx packets: [FAIL]
Traffic not reflected in the counter: 0 -> 0

Fix by skipping the test when used with veth pairs.

Fixes: 813f97a26860 ("selftests: forwarding: Add a tunnel-based test for L3 HW stats")
