io_uring: kill io_uring userspace examples
There are tons of io_uring tests and examples in liburing and on the
Internet. If you're looking for a benchmark, io_uring-bench.c is just an
acutely outdated version of fio/io_uring. And for basic condensed init
template for likes of selftests take a peek at io_uring_zerocopy_tx.c.
Kill tools/io_uring/, it's a burden keeping it here.
