linux: disable SQPOLL io_uring by default (#4492)
The SQPOLL io_uring instance wasn't providing consistent behaviour to
users depending on kernel versions, load shape, ... creating issues
difficult to track and fix. Don't use this ring by default but allow
enabling it by calling `uv_loop_configure()` with
`UV_LOOP_ENABLE_IO_URING_SQPOLL`.
