leak tests: mark some misc tests as passing with SANITIZE=leak

As in 7ff24785cb7 (leak tests: mark some misc tests as passing with
SANITIZE=leak, 2021-10-12) continue marking various miscellaneous
tests as passing when git is compiled with SANITIZE=leak. They'll now
be listed as running under the "GIT_TEST_PASSING_SANITIZE_LEAK=true"
test mode (the "linux-leaks" CI target).
