selftests/xsk: Query for native XDP support

Browse source

Currently, xdpxceiver assumes that underlying device supports XDP in
native mode - it is fine by now since tests can run only on a veth pair.
Future commit is going to allow running test suite against physical
devices, so let us query the device if it is capable of running XDP
programs in native mode. This way xdpxceiver will not try to run
TEST_MODE_DRV if device being tested is not supporting it.
