io_uring_prep_cmd() puts the optval pointer into the 64-bit optval field
of the SQE with a plain cast, which warns on 32-bit architectures:
mini_liburing.h:272:23: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
Cast through uintptr_t, and include <stdint.h> for it.

Instead of defining basic io_uring functions in the test case, move them
to a common directory, so, other tests can use them.
This simplify the test code and reuse the common liburing
infrastructure. This is basically a copy of what we have in
io_uring_zerocopy_tx with some minor improvements to make checkpatch
happy.
A follow-up test will use the same helpers in a BPF sockopt test.
