Make sure only sockopt programs can be attached to the setsockopt
and getsockopt hooks.

Run all existing test cases with the attachment created via
BPF_LINK_CREATE. Next commit will add extra test cases to verify
link_create attach_type enforcement.

Expand the sockopt test to use also check for io_uring {g,s}etsockopt
commands operations.
This patch starts by marking each test if they support io_uring support
or not.
Right now, io_uring cmd getsockopt() has a limitation of only
accepting level == SOL_SOCKET, otherwise it returns -EOPNOTSUPP. Since
there aren't any test exercising getsockopt(level == SOL_SOCKET), this
patch changes two tests to use level == SOL_SOCKET, they are
"getsockopt: support smaller ctx->optlen" and "getsockopt: read
ctx->optlen".
There is no limitation for the setsockopt() part.
Later, each test runs using regular {g,s}etsockopt systemcalls, and, if
liburing is supported, execute the same test (again), but calling
liburing {g,s}setsockopt commands.
This patch also changes the level of two tests to use SOL_SOCKET for the
following two tests. This is going to help to exercise the io_uring
subsystem:
* getsockopt: read ctx->optlen
* getsockopt: support smaller ctx->optlen

The sockopt test invokes test__start_subtest and then unconditionally
asserts the success. That means that even if deny-listed, any test will
still run and potentially fail.
Evaluate the return value of test__start_subtest() to achieve the
desired behavior, as other tests do.

Instead of assuming EFAULT, let's assume the BPF program's
output is ignored.
Remove "getsockopt: deny arbitrary ctx->retval" because it
was actually testing optlen. We have separate set of tests
for retval.

Convert the selftest to use the preferred ASSERT_* macros instead of the
deprecated CHECK().

Convert all the uses of legacy low-level BPF program loading APIs
(mostly bpf_load_program_xattr(), but also some bpf_verify_program()) to
bpf_prog_load() uses.
