Use MEM_REGION_PT to indirectly specify memslot '0' instead of hardcoding
the memslot in s390's virtual memory allocator, as a first step towards
taking the allocation type instead of the exact, raw memslot in the
physical memory allocator.

Note, the only tests that set MEM_REGION_PT to a memslot other than '0' are
arm64-only, i.e. s390 always uses memslot '0' for page tables.

No functional change intended.
