kernel - Reduce impact of write_behind on small/temporary files

* Do not start issuing write-behind writes until a file has grown past
  a certain size, otherwise we wind up issuing excessive I/O for
  small files and for temporary files which might be quickly deleted.

* Add vfs.write_behind_minfilesize sysctl (defaults to 10MB).
