Grant apps write access to returned vfat FDs.

Users can pick files from vfat devices through the Storage Access
Framework, which are returned through ParcelFileDescriptors.  Grant
apps write access to those files.  (Direct access to the files on
disk is still controlled through normal filesystem permissions.)
