Lorenzo Stoakes (ARM) 6b7460ad1a tools/testing/vma: expand VMA merge tests to assert anon pgoff ...

Now we have introduced the VMA anonymous page offset attribute and update
it when VMAs are manipulated, update VMA merge tests to assert that the
anonymous page offset is as expected.

Also update instances where we could use vma_start_pgoff() to do so.
