[PATCH] perf tool: Add missing subcommand `version`

[Sangwon Hong]

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
