[PATCH liburing v2] test/ringbuf-read: Delete `.ringbuf-read.%d` before exit

[Ammar Faizi <ammarfaizi2@gnuweeb.org>]

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. While in there, fix the exit code,
use T_EXIT_*.

v2:
  - Use T_EXIT_* for exit code (comment from Alviro).
