Check properly the connection tracking entry status configured running
bpf_ct_change_status kfunc.
Remove unnecessary IPS_CONFIRMED status configuration since it is
already done during entry allocation.

Test that the prog can read from the connection mark. This test is nice
because it ensures progs can interact with netfilter subsystem
correctly.

Add a test where we do a conntrack lookup on an existing connection.
This is nice because it's a more realistic test than artifically
creating a ct entry and looking it up afterwards.

Test cases we care about and ensure improper usage is caught and
rejected by the verifier.

bpf_prog_test_run is being deprecated in favor of the OPTS-based
bpf_prog_test_run_opts.
We end up unable to use CHECK in most cases, so replace usages with
ASSERT_* calls.

This tests that we return errors as documented, and also that the kfunc
calls work from both XDP and TC hooks.
