There is no "system key." Each manufacturer signs the platform with their own certificate (or even different certificates for different devices). If these apps are getting this permission at all, it will only be on a small subset of devices; there is no way to be signed to get such permissions on all devices. (And really, it would fundamentally be broken to put an app on market that is signed with a platform's cert, for this reason.)
Most likely this is either just some junk left in the app from development, or possibly the app developers are having their apps pre-installed on some devices and taking advantage of being able to get the permissions in that case. If you want to know if the permissions are being granted, just look at the output of "adb logcat" while installing the app; error messages will be printed for ones that can't be granted. And no, you can't install anything into /system from anywhere except a full system update. The /system partition is mounted read-only.
