Subject: [PATCH] test-lib: declare local variables as local
Message-ID: <81f43fbefde84ab7af9ee2ac760845b728a48ab5.1646861976.git.git@grubix.eu>

```
131b94a10a ("test-lib.sh: Use GLIBC_TUNABLES instead of MALLOC_CHECK_ on
glibc >= 2.34", 2022-03-04) introduced "local" variables without
declaring them as such. This conflicts with their use in some tests (at
least when running them with dash), leading to test failures in:

t0006-date.sh
t2002-checkout-cache-u.sh
t3430-rebase-merges.sh
t4138-apply-ws-expansion.sh
t4124-apply-ws-rule.sh

Declare those variables as local to let the tests pass again.
