Konstantin Belousov f40cb1c645 Update mtime for tmpfs files modified through memory mapping. Similar
to UFS, perform updates during syncer scans, which in particular means
that tmpfs now performs scan on sync.  Also, this means that a mtime
update may be delayed up to 30 seconds after the write.

The vm_object' OBJ_TMPFS_DIRTY flag for tmpfs swap object is similar
to the OBJ_MIGHTBEDIRTY flag for the vnode object, it indicates that
object could have been dirtied.  Adapt fast page fault handler and
vm_object_set_writeable_dirty() to handle OBJ_TMPFS_NODE same as
OBJT_VNODE.
