[PATCH] kselftest/filelock: plan for the five ofdlocks tests

[Danish Khateeb]

ofdlocks reports five results but plans for four, so even when they
all pass it ends with

  # Planned tests != run tests (4 != 5)

and exits with KSFT_FAIL, which run_kselftest.sh reports as a failure.

Notes:
    Tested on x86_64 with the kselftest build of ofdlocks:
    
    - Arch host (gcc 16.2, 7.2.6 kernel): before, all 5 pass but it exits 1
      with "Planned tests != run tests (4 != 5)"; after, 5/5 and exit 0.
    - Debian trixie guest (gcc 14.2, next-20260925): test 4 fails before and
      after this patch, because it memcmp()s two struct flock whose padding
      was never initialized (bytes 28-29 differ). Zhou Yuhang's "selftests:
      filelock: Initialize the flock to zero" [1] fixes that, and with both
      patches all 5 pass there too.
