bpftool: fix perf help message

Currently, bpftool perf subcommand has typo with the help message.

    $ tools/bpf/bpftool/bpftool perf help
    Usage: bpftool perf { show | list }
           bpftool perf help }

Since this bpftool perf subcommand help message has the extra bracket,
this commit fix the typo by removing the extra bracket.
