Move all BPF_CGROUP_INET6_POST_BIND and BPF_CGROUP_INET4_POST_BIND test

LOAD_REJECT test cases.

How is verbose used and is it still needed?

nit. ASSERT_OK_FD().
Since the test binds to a specific ip/port, please run it in its own netns. It
is easy to do with netns_new and netns_free, a recent example:
https://lore.kernel.org/bpf/20241020-syncookie-v2-1-2db240225fed@xxxxxxxxxxx/
The same netns can be reused for different subtests of this "sock_post_bind" test.
Others look good. Thanks for moving the test to test_progs.
