This patchset creates a selftest for the robust list interface, to track
regressions and assure that the interface keeps working as expected.

In this version I removed the kselftest_harness include, but I expanded the
current futex selftest API a little bit with basic ASSERT_ macros to make the
test easier to write and read. In the future, hopefully we can move all futex
selftests to the kselftest_harness API anyway.

Changes from v2:
- Create ASSERT_ macros for futex selftests
- Dropped kselftest_harness include, using just futex test API
- This is the expected output:
