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.
