perf sched: Make common options cascading

The -i and -v options can be used in subcommands so enable cascading the
sched_options.  This fixes the following inconvenience in 'perf sched':

  $ perf sched -i perf.data.sched  map
  ... (it works well) ...

  $ perf sched map  -i perf.data.sched
    Error: unknown switch `i'

   Usage: perf sched map [<options>]

          --color-cpus <cpus>
                            highlight given CPUs in map
          --color-pids <pids>
                            highlight given pids in map
          --compact         map output in compact mode
          --cpus <cpus>     display given CPUs in map

With this patch, the second command line works with the perf.data.sched
data file.
