The uuidgen(2) system call enforces a hard upper limit of 2048 UUIDs per
invocation. uuidgen(1) previously attempted to generate arbitrary counts
in a single call and allocated memory accordingly, leading to EINVAL
errors, unnecessary memory usage, and potential overflow risks.
Generate UUIDs in fixed-size batches, streaming output incrementally
while preserving existing semantics. Mirror the kernel limit explicitly
since it is not exposed via a public interface.
