perf tools: Fix counter sample frequency breakage
Commit 42e59d7d19dc4b4 switched to a default sample frequency of
1KHz, which overrides any user supplied count, causing sched, top
and timechart to miss events due to their discrete events
being flagged PERF_SAMPLE_PERIOD.
Override default sample frequency when the user profides a
period count, and make both record and top honor that user
supplied option.
