perf annotate: Get rid of annotation__scnprintf_samples_period() We have more current function tto get the title for annotation, which is hists__scnprintf_title. They both have same output as far as the annotation's header line goes. They differ in counting of the nr_samples, hists__scnprintf_title provides more accurate number based on the setup of the symbol_conf.filter_relative variable. Plus it also displays any uid/thread/dso/socket filters/zooms if there are set any, which annotation__scnprintf_samples_period does not.
