[PATCH 1/2] test-lib.sh: de-duplicate error() teardown code

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

De-duplicate the "finalize_junit_xml; GIT_EXIT_OK=t; exit 1" code
shared between the "error()" and "--immediate on failure" code paths,
in preparation for adding a third user in a subsequent commit.
