Benchmark: fixes, user_note, verifiable test data

* fix zlib display order
* fix cryptohash MiB/s calculation
* revision and params for other benchmarks
* allow attaching user note to bench result with -u
* don't inlcude the new result value bits if they are empty/invalid
  in bench_value_to_str(). bench_value_from_str() doesn't need to be modified.
* bench_results: clean old result cpu name for x86
* use problem_marker() from dmi_memory to mark old version bench results
* benchmark: verifiable test data size and content
  - The test data benchmark.data is stored in a file
    that could be edited to change the size or content.
    /* to guarantee size */
    gchar *get_test_data(gsize min_size);

    /* to checksum content */
    char *md5_digest_str(const char *data, unsigned int len);
