Applications installed on the /system partition are not subject to being placed into the "stopped" state after installation. If you have root, you can do,

$ adb root
$ adb remount
$ adb push your.apk /system/app

EDIT: Keep in mind that different versions of Android locate system APKs in different places. For example, Android 8 puts them under /system/app//.apk. Shell into your device and poke around and follow the same scheme used for other system APKs.
