de9c8d848d selftests/bpf: S/iptables/iptables-legacy/ in the bpf_nf and xdp_synproxy test 
The recent vm image in CI has reported error in selftests that use
the iptables command.  Manu Bretelle has pointed out the difference
in the recent vm image that the iptables is sym-linked to the iptables-nft.
With this knowledge,  I can also reproduce the CI error by manually running
with the 'iptables-nft'.

This patch is to replace the iptables command with iptables-legacy
to unblock the CI tests.

b06b45e82b selftests/bpf: add tests for bpf_ct_set_nat_info kfunc 
Introduce self-tests for bpf_ct_set_nat_info kfunc used to set the
source or destination nat addresses/ports.

f7c946f288 selftests/bpf: fix ct status check in bpf_nf selftests 
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.

e2d75e954c selftests/bpf: Add tests for writing to nf_conn:mark 
Add a simple extension to the existing selftest to write to
nf_conn:mark. Also add a failure test for writing to unsupported field.

99799de2cb selftests/bpf: Add connmark read test 
Test that the prog can read from the connection mark. This test is nice
because it ensures progs can interact with netfilter subsystem
correctly.

e81fbd4c1b selftests/bpf: Add existing connection bpf_*_ct_lookup() test 
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.

04fcb5f9a1 selftests/bpf: Migrate from bpf_prog_test_run 
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.
