[PATCH 23/27] t3600: mark git command as failing

In a future patch, we plan on running tests with `set -o pipefail`.
Since we intentionally induce SIGPIPE, before the return code
was being masked away. However, now `git rm` will cause an error code to
be returned because of the SIGPIPE.

Mark the failing command with `test_must_fail ok=sigpipe` so that
failures induced by SIGPIPE don't propogate.
