sched: remove unused fields from struct rq

Browse source

Impact: cleanup, new schedstat ABI

Since they are used on in statistics and are always set to zero, the
following fields from struct rq have been removed: yld_exp_empty,
yld_act_empty and yld_both_empty.

Both Sched Debug and SCHEDSTAT_VERSION versions has also been
incremented since ABIs have been changed.

The schedtop tool has been updated to properly handle new version of
schedstat:
