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
