Kernel: Stop allocating page tables from the super pages pool

We now use the regular "user" physical pages for on-demand page table
allocations. This was by far the biggest source of super physical page
exhaustion, so that bug should be a thing of the past now. :^)

We still have super pages, but they are barely used. They remain useful
for code that requires memory with a low physical address.

Fixes #1000.
