blktrace: Create empty output files for non-existent cpus
When CPU number space is sparse, we don't start threads for non-existent CPUs. As a result, there are no output files created for these CPUs which confuses tools like blkparse which expect that CPU numbers are contiguous. Create fake empty files for non-existent CPUs so that other tools don't have to bother. Note that in network mode, the server will create all files in the range 0..max_cpus automatically.
