selftests/mm: make file-backed THP split work by writing PMD size data
Commit acd7ccb284b8 ("mm: shmem: add large folio support for tmpfs")
changes huge=always to allocate THP/mTHP based on write size and
split_huge_page_test does not write PMD size data, so file-back THP is not
created during the test. Fix it by writing PMD size data.
