[PATCH liburing v1] test/ringbuf-read: Delete `.ringbuf-read.%d` before exit

[Ammar Faizi]

From: Ammar Faizi <ammarfaizi2@gnuweeb.org>

Running test/ringbuf-read.t leaves untracked files in git status:

  Untracked files:
    (use "git add <file>..." to include in what will be committed)
          .ringbuf-read.163521
          .ringbuf-read.163564
          .ringbuf-read.163605
          .ringbuf-read.163648

Make sure we unlink it properly.

Yes, we should. I forgot, will send a v2.
