selftests/vm: cow: basic COW tests for non-anonymous pages
Let's add basic tests for COW with non-anonymous pages in private
mappings: write access should properly trigger COW and result in the
private changes not being visible through other page mappings.
Especially, add tests for:
* Zeropage
* Huge zeropage
* Ordinary pagecache pages via memfd and tmpfile()
* Hugetlb pages via memfd
Fortunately, all tests pass.
