keymaster restore: warn when pin, password or pattern is enabled

Starting in Android 10, zygote relies on stored inodes in order
to find packages in the user's CE directories. Since TWRP cannot
force inode creation on restore, we warn the user to remove their
pin before restoring their backup. Otherwise zygote may not load
properly in Android. This will force the system to update the
inode cache.

The user can then re-add their security settings to android.
