kernel: fix yielding between tasks with same deadline

Browse source 
Previously two tasks with the same deadline and priority would
always have `z_is_t1_higher_prio_than_t2` `true` in both directions.

This is logically inconsistent, and results in `k_yield` not actually
yielding between identical threads.
