Update sby_engine_abc.py

Browse source 
ABC will sometimes return negative frame numbers when proving by convergence, e.g.
```
engine_0: Proved output 1 in frame -698905656 (converged).
engine_0: Proved output 4 in frame -698905656 (converged).
```
This change fixes these properties being missed and causing the engine status to return UNKNOWN due to `proved_count != len(proved)`.
