iostats: reimplement iostats as a 9p filter instead of duplicating exportfs
old iostats failed to work when builidng the kernel due to old bugs
that where already fixed in exportfs. instead of backporting the fixes,
reimplement iostats as a filter that sits between exportfs and the
process mount. from users perspective, theres no difference.
the result is much smaller and can handle everything that exportfs
can like /srv.
