Commit 3105b86a defined numabalancing_enabled to control the enabling
and disabling of automatic NUMA balancing, but it is never used.
I believe the intention was to use this in place of
sched_feat_numa(NUMA).
Currently, if SCHED_DEBUG is not defined, sched_feat_numa(NUMA) will
never be changed from the initial "false".
