[PATCH 7/9] test-tool bloom: fix a memory leak

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

Fix memory leaks introduced with these tests in f1294eaf7fb (bloom.c:
introduce core Bloom filter constructs, 2020-03-30), as a result we
can mark almost the entirety of t0095-bloom.sh as passing with
SANITIZE=leak using "TEST_PASSES_SANITIZE_LEAK=true", there's still an
unrelated memory leak in "git commit" in one of the tests, let's skip
that one under SANITIZE_LEAK for now.
