perf help: Add missing subcommand `version`

There isn't subcommand `version` when typing `perf help`.

Before :

  $ perf help | grep version
   usage: perf [--version] [--help] [OPTIONS] COMMAND [ARGS]

So add perf-version in command-list.txt for listing it when typing `perf
help`.

After :

$ perf help | grep version

 usage: perf [--version] [--help] [OPTIONS] COMMAND [ARGS]
   version         display the version of perf binary
