Use new libosmovty cpu sched config features

Using the new libosmovty features allow for:
* Setting different cpu-affinity masks for each thread in the process,
  both at startup through .cfg file as well as changing it at runtime.
* Unified VTY interface to change the scheduling policy of the process
  inherited by all osmocom processes enabling the feature.
