perf tools: Add 'I' event modifier for exclude_idle bit

Adding 'I' event modifier to have complete set of modifiers for
perf_event_attr:exclude_* bits.

Any event specified with 'I' modifier will have the
perf_event_attr:exclude_idle bit set.

  $ perf record -e cycles:I -vv ls 2>&1 | grep exclude_idle
  exclude_hv          0    exclude_idle        1

Adding automated tests.
