aufs: bugfix, the external patch for mmap is always required

In order to support mmap(2), aufs provided two levels.
- native support in purely aufs code.
- optional support, particulary for the pathnames printed in
  /proc/PID/maps, by the external aufs3-proc_map.patch and
  CONFIG_AUFS_PROC_MAP. The patch touches several mainline files out of
  aufs.
This (dirty) approach is described in
Documentation/filesystems/aufs/design/06mmap.txt.

Wojciech Kocjan reported a problem about the second (above), and I found
it is alwasy necessary (instead of optional).
