acrntrace: Add opt to specify the cpus where we should capture the data

Browse Source 
This patch adds one new option '-a' to specify the cpus where we should
capture the trace data. If the this option is not set or set with wrong
optarg, we will capture the trace data of all possible cpus.

The set of the cpus can be specified as A,B,C, or A-C, or A,D-F, and so on.
