tests: improve scripts on rocm v2.6, and do more check

'rocminfo' output format on v2.6 is slightly different, and thus
cache capacity and cache linesize can be incorrectly obtained.
Example: 'L1: 16KB' vs. 'L1: 16(0x10) KB'. This patch fixes the
formatting issue, and further does more check on profiled .csv
file.
