[PATCH 1/3] test/bpf: skip some testing if null net driver not present

Some of the BPF tests require the net/null driver to be present, so skip
those tests if it's not found. If the early part of the tests fail,
return that failure - on if they succeed do we return skipped on the
missing dependency.
