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")
