In fact, we can define our own

Hi DanielXu, I have pushed the libb
ing two tests. This is going to help to exercise the io_uring
subsystem:
* getsockopt: read ctx->optlen
* getsockopt: support smaller ctx->optlen

Expand the BPF sockopt test to use also check for io_uring

Create infrastructure to run io_uring tests using the mini_liburing
