Add --rdonly_shmem_buf option to kublk that registers shared memory buffers with UBLK_SHMEM_BUF_READ_ONLY (read-only pinning without FOLL_WRITE) and mmaps with PROT_READ only. Add test_shmemzc_04.sh which exercises the new flag with a null target, hugetlbfs buffer, and write workload. Write I/O works because the server only reads from the shared buffer — the data flows from client to kernel to the shared pages, and the server reads them out.
