Interposer patch may break some SEP functionality

[Cryptiiiic]

I noticed in commit 52358b3 you made that specific method of interposer patch for iOS 12 and lower only. Why exactly? In my testing this will cause some SEP panics on 13/14/15. I'm specifically refering to this if block: HERE If I comment out this if, it won't panic on 13/14/15. Btw this method of patching ensures the interposer function fully executes before we modify the return value. I assume the function sets up some stuff needed by SEP?
