Support database rebuild disabling when USB is connected for all e200 OF versions. Some people may have to update the OF (to any version they want) using sansapatcher before it will work. This just ensures that the NVPARAMS are in a good state and we can be sure where to look for the rebuild flag.The c200 OF doesn't reboot before rebuilding the database, so our trick won't ever work there.
