Donet Tom 08ff89b565 selftests/mm: add fork inheritance test for ksm_merging_pages counter ...

Add a new selftest to verify whether the `ksm_merging_pages` counter in
`mm_struct` is not inherited by a child process after fork.  This helps
ensure correctness of KSM accounting across process creation.
