Make phh-securize.sh work with current Magisk

Browse Source 
Magisk 21.0 changed the mount path, we have to get it with "magisk --path" now.
This is used to get where the system partition is mounted.

The phh-su bind-mount is on /system/xbin/su, even with Magisk.
But we still have to unmount it, in order to remove the empty "su" file on the system partition.
