perf evsel: Update sample_size when setting sample_type bits
We use evsel->sample_size to detect underflows in
perf_evsel__parse_sample, but we were failing to update it after
perf_evsel__init(), i.e. when we decide, after creating an evsel, that
we want some extra field bit set.
Fix it by introducing methods to set a bit that will take care of
correctly adjusting evsel->sample_size.
