core: allow to read states for non-contract verifications

Browse source 
C# does it this way now:
  callFlags = !witness.VerificationScript.IsStandardContract() ? CallFlags.ReadStates : CallFlags.None

So non-standard scripts _always_ have access to state and standards ones just
don't care (their code is known and it doesn't touch state).
