Subject: [PATCH mm-unstable v1 2/4] selftests/vm: madv_populate: fix missing MADV_POPULATE_(READ|WRITE) definitions

The tests fail to compile in some environments (e.g., Debian 11.5 on x86).
Let's simply conditionally define MADV_POPULATE_(READ|WRITE) if not
already defined, similar to how the khugepaged.c test handles it.

Fixes: 39b2e5cae43d ("selftests/vm: make MADV_POPULATE_(READ|WRITE) use in-tree headers")
