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]
