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.
