perf tools: Put proper period for for samples without PERIOD sample_type
We use PERF_SAMPLE_PERIOD sample type only for frequency
setup -F (default) option. The -c does not need store period,
because it's always the same.
In -c case the report code uses '1' as period. Fixing
it to perf_event_attr::sample_period.
