Arnd Bergmann 72d42504bd ovl: select EXPORTFS
We get a link error when EXPORTFS is not enabled:

ERROR: "exportfs_encode_fh" [fs/overlayfs/overlay.ko] undefined!
ERROR: "exportfs_decode_fh" [fs/overlayfs/overlay.ko] undefined!

This adds a Kconfig 'select' statement for overlayfs, the same way that
it is done for the other users of exportfs.

Fixes: 3a1e819b4e80 ("ovl: store file handle of lower inode on copy up")
