These test scripts have not changed at all recently, but topics in seen
have caused these to trigger the linux-leaks test. It has been reported
on list, so let's fix the claim that these are leak free and when
someone investigates and fixes the problem, they can turn it back on.

leak tests: ignore some new leaks in a few tests
linux-leaks passes when 'seen' is merged with this topic. A better fix
is probably to bisect to determine which topic caused the memory leak
and plug the leak in that topic (because these test scripts did not have
any changes since the version when they previously passed), but a couple
of quotes:
""" This is sort of water under the bridge, as the other topic is
already in 'master', but come to think of it, the strategy we used with
TEST_PASSES_SANITIZE_LEAK variable was misguided.
... I am tempted to drop the "TEST_PASSES" bit from this script for now,
""" (from https://lore.kernel.org/git/xmqqee6dz5s9.fsf@gitster.g/)
""" But as to the "roadblock" I don't mind the
TEST_PASSES_SANITIZE_LEAK=true being removed from the script at the
slightest sign of trouble. Nobody should have to shift gears and chase
down some memory leak... """ (from
https://lore.kernel.org/git/211217.86a6gyyihr.gmgdl@evledraar.gmail.com/)

I think this problem was likely introduced by a faulty patch in
c2dbe00466 (Merge branch
'ps/avoid-unnecessary-hook-invocation-with-packed-refs' into seen,
2022-01-12), specifically 2e6b34bb1b (refs: open-code deletion of packed
refs, 2022-01-07).
But the newer version 69840cc0f7 of the same patch (merged via
17d1824959) fixes the leak. As a result, all three of those once-failing
tests now pass on 'seen' even when built with SANITIZE=leak.
We should be able to discard this patch as a result.
Thanks,
Taylor
