Tomasz Zawadzki 66a5b406cb scheduler_dynamic: lower the idle thread limit
Limit of 50% to mark thread as active or idle
didn't allow for multiple active threads to be placed
on single core.

Lowering the limit to 20% will allow that and force
more threads to be actively balanced.

Removing the limit was considered, but that would
cause too much thread moves when a thread with load
in single digits increased briefly. Either
due to actually doing any operation or placement
of other threads on the same core.
