[PATCH v1 5/5] perf evsel: Make unknown event names more unique

[Ian Rogers]

In situations like the perf data converter the evsel__name will be
used to create babeltrace events. If the events have the same name
then creation can fail. Avoid these failures by including more
information into the unknown event names.
