[Versioning] Better and smarter for update and sept

- Still compatible with old hekate.
- Allows for hotfix control
- Sept is now copied from actual running payload, negating the need to check update.bin
- If a foreign payload is found in sept then it is renamed and hekate copies itself. After sept run, it renames it back and continues with boot.
