This adds set of tests which use io_uring for rx/tx. This test suite is
implemented as separated util like 'vsock_test' and has the same set of
input arguments as 'vsock_test'. These tests only cover cases of data
transmission (no connect/bind/accept etc).

This will fails if for example we call make with more targets,
e.g. `make vsock_test vsock_uring_test`.

I'd suggest to use something like this:

Shoud we add this new test to the "test" target as well?
