perf list: Add debug support for outputing alias string
For debugging and testing it is useful to see the converted alias string. Add support to perf stat/record and perf list to print the alias conversion. The text string is saved in the alias structure. For perf stat/record it is folded into the normal -v. For perf list -v was taken, so we use --debug.
