add.c: refactor backup file modification checks
The previous implementation was overly complex with unnecessary checks and nested conditionals. By reordering the tests and changing them to all be checks for positive hash matches rather than non-matches, we can collapse several cases and make the process much more linear. This removes the need to set hash_orig = "" just to reach some of the checks and corrects a faulty assumption that files are equivalent when the hashing process fails.
