PR_SET_MM_MAP_SIZE is listed in the commit message but is not defined here.
Add its UAPI value, 15, alongside PR_SET_MM_MAP.

PR_SET_MM_MAP copies these values into current->mm, so this sets the process
break to a stack address before the test starts. Preserve the real break with
sbrk(0), as waiter_fn() does, and supply valid current values for the other
memory-map fields.

PR_SET_MM_MAP was added in Linux 3.18, while the CVE predates it. Add
`.min_kver = "3.18"` or report TCONF when this required operation is
unavailable instead of reporting TBROK.

Verdict - Needs revision
