ARM: Enable ARCH_HAS_DEBUG_VM_PGTABLE

Using the generic page table tests is nice for conformance
testing. After enabling this on Versatile Express with LPAE
and debug prints all tests pass on the classic MMU.

However with LPAE enabled we get this:
BUG: non-zero pgtables_bytes on freeing mm: -4096

This message comes from kernel/fork.c and not the test per
se.
