Include android.permission.ACCESS_SUPERUSER permission in the base API

Since we don't include this version of the su binary we need to
register this permission other wise if user installs Koush's Superuser
apk later all apps previously installed will not be granted
superuser permission as it, the permission, did not exist when apk
previously asked for permissions

This is a hack to avoid Android Issue 25906
 (https://code.google.com/p/android/issues/detail?id=25906)
