perf list: Fix --raw-dump option

Currently, 'perf list --raw-dump' requires extra arguments
(e.g., hw) to invoke, which breaks bash/zsh completion
(perf-completion.sh).

  $ perf list --raw-dump
    Error: unknown option `raw-dump'

     usage: perf list [hw|sw|cache|tracepoint|pmu|event_glob]

After,

  $ perf list --raw-dump
  cpu-cycles instructions cache-references cache-misses ...
