LAKITU: sched/fair: keep using upstream select_idle_sibling()

In patch 0959988c66be ("ANDROID: sched: EAS: take cstate into account
when selecting idle core"), a new implementation of
select_idle_sibling() was introduced, and have caused regression for
Dataflow.

This commit disables the flag sysctl_sched_cstate_aware which then
points the select_idle_sibling() function to the upstream version.
