MFC 319702: Fix an off-by-one error in the VM page array on some systems.

r313186 changed how the size of the VM page array was calculated to be
less wasteful.  For most systems, the amount of memory is divided by
the overhead required by each page (a page of data plus a struct vm_page)
to determine the maximum number of available pages.  However, if the
remainder for the first non-available page was at least a page of data
(so that the only memory missing was a struct vm_page), this last page
was left in phys_avail[] but was not allocated an entry in the VM page
array.  Handle this case by explicitly excluding the page from
phys_avail[].
