kernel - TMPFS - Stabilization pass, fix VM object leak, msync

* The swap vm_object backing regular files was not being deallocated
  properly and leaked kernel memory.

* Truncate deleted files a little earlier in the INACTIVE path.

* Set MNTK_NOMSYNC.  This prevents msync(), sync(), and the
  periodic filesystem syncer from flushing pages to swap.

  VM pages related to tmpfs are only flushed based on memory
  pressure.
