[PATCH 2/3] t/t5400-send-pack.sh: add test_when_finished commands

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

Change the tests in t/t5400-send-pack.sh to use test_when_finished to
unset git config variables that were set in the tests, e.g.:

    git config --unset $variable_they_set

This doesn't change the test behavior, but makes each test more
self-contained.
