[PATCH v2 0/7] leak tests: fix "test-tool" & other small leaks

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

Like my just-submitted series to mark existing tests as passing[1]
under the test mode added in ab/sanitize-leak-ci, this marks more
tests as passing, but here we need to fix some small memory
leaks. This goes on top of ab/sanitize-leak-ci.

See v1[1] for a more detailed summary, the only update here is to some
bad commit message grammar/phrasing in v1.
