test/scheduler: Use CPU list rather than cpumask

When we select CPUs for the scheduler tests we pick up all siblings
from given core. On some nodes in the CI these threads may have IDs
in ranges that simply overflow during the shift operation ( > 62).

To avoid this, use a list instead of a mask. Also, deny all threads
with IDs > 127 as DPDK doesn't support them anyway.
