tools: acrntrace: Make TSC frequency configurable

Browse Source 
Originally, acrntrace stores cpu frequency in output file and use it for time-based
analysis. Actually, we should use TSC frequency instead of cpu frequency.

This patch change to using TSC frequency for time-based analysis and introduce
an option "-f --frequency" to let user configure TSC frequency.
