aiger2: Resolve warnings 

- Remove unused statics CONST_FALSE and CONST_TRUE (which appear to have been folded into the `Index` declaration as CFALSE and CTRUE).
- Assign default value of EMPTY_LIT to `a` and `b` for comparison ops.
- Tag debug only variables with YS_MAYBE_UNUSED, don't assign unused variables (but continue to call the function because it moves the file pointer).
