Bug 22653: Remove unimplemented RotationPreventTransfers system preference

This removes the RotationPreventTransfers system preference
from updated and new installations.

To test:
- Verify you have the RotationPreventTransfers pref
- Apply patch and run database update
- Verify the preference no longer exists in your system
  - in the sys pref editor
  - in your database:

SELECT * from systempreferences WHERE variable = "RotationPreventTransfers";
