perf tools: Invert the sample_id_all logic
Instead of requiring that users of perf_record_opts set
.sample_id_all_avail to true, just invert the logic, using
.sample_id_all_missing, that doesn't need to be explicitely initialized
since gcc will zero members ommitted in a struct initialization.
Just like the newly introduced .exclude_{guest,host} feature test.
