perf list: Honour 'event_glob' whem printing selectable PMUs

Some PMUs, like the 'intel_bts' one can be used as an event name, i.e.:

	$ perf record -e intel_bts:// usleep 1

Is a valid event name.

But the code printing such PMUs was not honouring the 'event_glob'
parameter, so the following line was always appearing:

  $ intel_bts//                                        [Kernel PMU event]

Fix it:

  $ [acme@felicio linux]$ perf list data

  List of pre-defined events (to be used in -e):

    uncore_imc/data_reads/                             [Kernel PMU event]
    uncore_imc/data_writes/                            [Kernel PMU event]
