Fixed the app getting stuck when enabling it on newer root solutions (through a Magisk/KernelSU/APatch module)

Hi, given that some newer root solutions don't have the supolicy binary anymore, P2oggle gets stuck after trying to toggle on the superuser functionality due to this:

p2oggle/app/src/main/java/eu/biqqles/p2oggle/Device.kt

Lines 64 to 66 in b27a5bb

	val supolicy = "supolicy --live " +
	"'allow appdomain input_device dir search' " + // directory rule
	"'allow appdomain input_device chr_file { getattr read open }'" // character device rule

To solve it I've created a tiny Magisk/KernelSU/APatch module that adds a dummy supolicy shell script under /system/bin (that just returns 0) and a sepolicy.rules file that applies the same SELinux rules that the app usually does.

allow appdomain input_device dir search
allow appdomain input_device chr_file { getattr read open }

That's it, after installing that P2oggle 1.2 works fine again. You can download it from here: t2oggle-compat.zip

It's only a couple of lines, so it should be easy to inspect and audit. Hope that helps.

Thanks for the great app, by the way. It's very well done, and the programmable physical button is super useful. :)

Actually, even easier; just alias it by making our supolicy call magiskpolicy:

#!/system/bin/sh
magiskpolicy "$@"

That's it: p2oggle-compat-v2.zip
