Individual workers now pick the Nth item out of currently configured CPU set rather than overriding an existing config. This allows to limit the cpu set more flexibly by the parent, e.g. using taskset. Additionally, before starting the workers, the manager now performs a scan for other Qemu instances in the system and removes their respective pinned CPUs from the own available set. Together, this should avoid the need for manually checking available CPUs and defining --cpu-offset for kafl_fuzz.py
