kernel - VM rework part 19 - Cleanup

* vmpageinfo breaks down the kernel load size, vm_page_array
  size, and buffer headers for the buffer cache, all of which
  are major boot-time wired kernel memory.

  Note that the vm_page_array[] uses 3.1% of physical memory.
  Its a lot, but there is no convenient way to make it less.
