10836d9f9a perf tests attr: Fix task term values

need it.

We have a test to detect to highest precise possible, so test can't just
predict precise_ip value.

5ff0cf421c perf tests attr: Fix sample_period setup 
The final period can differ from what user specifies on command line due
to the perf_event_max_sample_rate sysctl setup.

Thus we can't predixt the sample_period value any more.

5ced95b237 perf tests attr: Add 1s for exclude_kernel and task base bits 
There's an event open fallback which set exclude_kernel=1 in case use
does not have enough privileges. Adding both 0|1 for this attribute,
because we don't know what value it is.

75226c577c perf tests: Fix attr tests size values to cope with machine state on interrupt ABI changes 
Following change adjusted 'struct perf_event_attr', but let
the attr test's sizes untouched:
  60e2364e60 perf: Add ability to sample machine state on interrupt

  [jolsa@krava perf]$ ./perf test attr -vv
  --- start ---
  test child forked, pid 9719
  running './tests/attr/test-stat-group1'
    'PERF_TEST_ATTR=/tmp/tmp4drvul ./perf stat -o /tmp/tmp4drvul/perf.data -e '{cycles,instructions}' kill >/dev/null 2>&1' ret 1
  expected size=96, got 104
  FAILED './tests/attr/test-stat-group1' - match failure

Adjusting test size values for attr test.

66cd3f3a6c perf tests: Fix exclude_guest|exclude_host checking for attr tests 
We have a one of the event open fallback case in __perf_evsel__open
where we zero exclude_guest|exclude_host fields.

This means there's no way for attr tests to find out what's the right
value for those fields, so we need to check for both 0 and 1. Luckily we
still have other event parsing tests for those fields.

62b807f649 perf evsel: No need to always ask for PERF_FORMAT_TOTAL_TIME_{ENABLED,RUNNING} 
This is needed, so far, just in 'perf stat', to scale counters, so don't
unconditionally ask for them in the perf_evsel__config() method.

3a5afaec59 perf evsel: No need to always ask for PERF_FORMAT_ID in read_format 
Instead make perf_evlist__confir_attrs use perf_evsel__set_sample_id()
when having more than one event, that way only if we have multiple
events we'll ask to have the event ids returned when we read its file
descriptors.

need for 'optional' field.. old version removal leftover.
