This is v2 of the series to migrate futex functional tests to the harness.

Changes in v2:
- Move is_futex_waitv_supported() helper to a shared header (include/futex2test.h)
  to avoid duplication, as suggested by André Almeida.
- Call is_futex_waitv_supported() check at the start of TEST(waitv) in
  futex_wait_timeout.c for consistency.

Original description:
This series refactors futex functional tests to use the kselftest_harness.h
framework, fixing inconsistencies on older kernels where some syscalls
are missing, and corrects the validation logic in waitv negative tests.
