[PATCH 3/6] auto-crlf tests: check "git checkout" exit code

["Ævar Arnfjörð Bjarmason" <avarab@gmail.com>]

Don't hide the exit code from the "git checkout" we run to checkout
our attributes file.

This fixes cases where we'd have e.g. missed memory leaks under
SANITIZE=leak, this code doesn't leak (the relevant "git checkout"
leak has been fixed), but in a past version of git we'd continue past
this failure under SANITIZE=leak when these invocations had errored
out, even under "--immediate".
