description:
We track page modified info with PG_CLEAN, so make clear_modify
return false.  This makes rump lfs unmount work on platforms which
use the pmap stub (i.e. non-x86, which already returned false here).
Otherwise, lfs would hang itself trying to flush some buffers but
couldn't fill a segment and therefore wouldn't actually write
anything.
