Subject: [PATCH v1 1/3] perf completion: Restrict completion of events to events

perf list will list libpfm4 events and metrics which aren't valid
options to the '-e' option. Restrict the events gathered so that
invalid ones aren't shown.

Before:
$ perf stat -e <tab><tab>
Display all 633 possibilities? (y or n)

After:
$ perf stat -e <tab><tab>
Display all 375 possibilities? (y or n)
