[PATCH 4/4] t/lib-git-daemon: use test_match_signal

[Jeff King <peff@peff.net>]

When git-daemon exits, we expect it to be with the SIGTERM
we just sent it. If we see anything else, we'll complain.
But our check against exit code "143" is not portable. For
example:

  $ ksh93 t5570-git-daemon.sh
  [...]
  error: git daemon exited with status: 271

We can fix this by using test_match_signal.
