Log Message:
-----------
sys/linux: support large sqe/cqe in io_uring custom syz calls

Currently, even when the fuzzer attempts to set flags like IORING_SETUP_CQE32
or IORING_SETUP_SQE128, the custom syscalls explicitly ignore them.

But this limits the fuzzer's coverage and it is essential especially for
IORING_OP_URING_CMD ops.

The proposed fix should usually work. However, if params intended for
one ring are passed to another, this will fail.

Fixes #4531
