Some CI environments do not permit unprivileged processes to increase FIFO buffer sizes, even when the requested size is below the system maximum. The log_pipe AuTest treats this kernel policy as a product failure and cannot run in those environments. This makes the test accept only the corresponding `Operation not permitted` diagnostic when the FIFO remains unchanged, while continuing to reject other errors and fatal diagnostics. It also waits briefly for asynchronous diagnostic output before deciding whether the size check failed.
