Fix retaining disabled ROM apps in some cases again

[Rev4N1]

At least on my setup on first install it was disabling correctly, on reflash/update the module stopped disabling and if I reflashed it was disabled again.

I'm disabling an app inside system_ext

On KernelSU and I am guessing also APatch on first install before reboot the folder for disabling is created inside "$MODPATH/system":

ls -l /data/adb/modules_update/playintegrityfix/system
drwxr-xr-x    3 root     root          4096 Oct 30 23:01 system_ext

After rebooting, the folder gets moved to the root of the module and a system link is generated:

ls -l /data/adb/modules/playintegrityfix/system
lrwxrwxrwx 1 root root 13 2024-10-30 23:01 system_ext -> ../system_ext

ls -l /data/adb/modules/playintegrityfix/system_ext
drwxr-xr-x 4 root root 4096 2024-10-30 23:01 app

So if you don't copy the referenced folder instead of the syslink after the reflash and rebooting, the syslink will be pointing into a missing folder.

I tested this on KernelSU and Magisk and on my end everything holds correctly.

I'm also removing the -r because its implicit in -a

Thanks for another great contribution! This was the last thing I had on my to-do list to look into before v12 actually, but you beat me to it! 😃

The tester I had lined up confirmed it working with Xiaomi.eu and APatch. 🤘

We can call CI # 339 340 a release candidate unless you've got some other improvements in mind. 👍
