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.
