perf evsel: Decode read_format and sample_type in perf_evsel__fprintf

Before those fields showed just a number, now it decodes each bit:

[root@sandy linux]# perf evlist -v
cycles: sample_freq=4000, size: 96, sample_type: IP|TID|TIME|CPU|PERIOD, read_format: TOTAL_TIME_ENABLED|TOTAL_TIME_RUNNING|ID, disabled: 1, inherit: 1, mmap: 1, comm: 1, freq: 1, sample_id_all: 1, exclude_guest: 1
