perf tools: add perf_evlist__terminate() for terminate

hulk inclusion
category: bugfix
bugzilla: 24005
CVE: NA

-------------------------------------------

In __cmd_record(), when receiving SIGINT(ctrl + c), a done flag will
be set and the event list will be disabled by perf_evlist__disable()
once.

While in auxtrace_record.read_finish(), the related events will be
enabled again, if they are continuous, the recording seems to be endless.

Mark the evlist's state as terminated, preparing for the following fix.
