beam_utils: Simplify the return value for check_liveness/3
check_liveness/3 returns {unknown,State} if an instruction is not handled. All callers will handle 'unknown' the same way as 'used'. Therefore, we can simplify the code and improve the coverage if we return {used,State} instead of {unknown,State}.
