iommufd/selftest: Fix tests to use MOCK_PAGE_SIZE based buffer sizes

Browse Source 
commit a9af47e382 ("iommufd/selftest: Test IOMMU_HWPT_GET_DIRTY_BITMAP")
added tests covering edge cases in the boundaries of iova bitmap. Although
it used buffer sizes thinking in PAGE_SIZE (4K) as opposed to the
MOCK_PAGE_SIZE (2K) that is used in iommufd mock selftests. This meant that
isn't correctly exercising everything specifically the u32 and 4K bitmap
test cases. Fix selftests buffer sizes to be based on mock page size.
