Cannot disable com.motorola.ccc.ota
To stop OTA updates (and notifications) on Moto devices, you don't use Package Manager, you will need to "freeze" the service...

Google Play Store has many apps that will allow you to 'freeze' the OTA Update service. Titanium Backup is a common example.

Alternatively, with a 'root access' file explorer, you can delete or rename the following files:  

/system/etc/security/otacerts.zip
/system/priv-app/3c_ota/3c_ota.apk  

These additional files can be removed or renamed: (If you still get an OTA Update notification)  

/system/priv-app/3c_checkin/3c_checkin.apk
/system/priv-app/3c_devicemanagement/3c_devicemanagement.apk
/system/priv-app/3c_notification/3c_notification.apk
