KAFKA-6292; Improve FileLogInputStream batch position checks to avoid type overflow (#4928)

Switch from sum operations to subtraction to avoid type casting in checks and type overflow during `FlieLogInputStream` work, especially in cases where property `log.segment.bytes` was set close to the `Integer.MAX_VALUE` and used as a `position` inside `nextBatch()` function.
