Add io_uring integration tests and workload scenarios

Implement iouring_test.go with tests for io_uring_setup, io_uring_enter,
and io_uring_register tracepoints. Add corresponding workload scenarios
using raw syscalls (425, 426, 427) since Go stdlib doesn't wrap io_uring
on amd64.

- iouring-setup: creates io_uring instance via io_uring_setup(2)
- iouring-enter: creates ring, calls io_uring_enter(2) with zero ops
- iouring-register: creates ring, calls io_uring_register(2) with PROBE

Task #343
