* All the IPermissionController related functions are guarded by
`if !defined(__ANDROID_VNDK__)` [1], meaning they're not fully
accessible to vendors.
* Since we know these are mainly used to check whether an app or
process has a required permission, simply provide an stub that
returns true no matter what the permission / caller are.
