Restrict initial location for ACTION_OPEN_DOCUMENT/_TREE

Implement privacy restriction introduced in Android 11 that application
are not allowed to request initial location for intent actions
ACTION_OPEN_DOCUMENT and ACTION_OPEN_DOCUMENT_TREE to be /Android/data/,
/Android/obb/, /Android/sandbox/ and all their subdirectories.
If an application does request the initial location to be one of these
directories (or their subdirs) redirect to the default location - last
accessed stack.
