perf tools: Enhance the matching of sub-commands abbreviations
We support short command 'rec*' for 'record' and 'rep*' for 'report' in lots of sub-commands, but the matching is not quite strict currnetly. It may be puzzling sometime, like we mis-type a 'recport' to report but it will perform 'record' in fact without any message. To fix this, add a check to ensure that the short cmd is valid prefix of the real command.
