Grant platform apps access to /mnt/media_rw.

Browse source 
Raw physical storage devices are mounted by vold under /mnt/media_rw
and then wrapped in a FUSE daemon that presents them under /storage.

Normal apps only have access through /storage, but platform apps
(such as ExternalStorageProvider) often bypass the FUSE daemon for
performance reasons.
