Fix three miscalculations in amount of boot pages:

o Most of startup zones have struct uma_slab embedded into the slab,
  so provide macro UMA_SLAB_SPACE and use it instead of UMA_SLAB_SIZE,
  when calculating how many pages would certain kind of allocations
  require. Some zones are offpage, so we might have a positive inaccuracy.
o The keg for the zone of zones is allocated "dynamically", so we
  need +1 when calculating amount of pages for kegs. [1]
o The zones of zones and zones of kegs have arbitrary alignment of 32,
  and this also needs to be accounted for. [2]

While here, spread more comments and improve diagnostic messages.
