tools/testing/vma: convert bulk of test code to vma_flags_t

Convert the test code to utilise vma_flags_t as opposed to the deprecate
vm_flags_t as much as possible.

As part of this change, add VMA_STICKY_FLAGS and VMA_SPECIAL_FLAGS as
early versions of what these defines will look like in the kernel logic
once this logic is implemented.
