Update syno_hdd_db.sh

- Added support for SAS drives.
- Now gets HDD/SSD/SAS drive model number with smartctl instead of hdparm.
- Now prevents DSM auto updating the drive database.
- Disable "support_disk_compatibility" (that was added in v1.0.6) is now optional.
  - Run script with -f or -force to disable "support_disk_compatibility".
  - If run without -f or -force "support_disk_compatibility" is re-enabled.
