[PATCH 0/9] test-tool: fix memory leaks

This is a series of trivial leak-fixes which allows us to mark various tests as entirely passing under SANITIZE=leak, the reasn they weren't passing before was because we'd spot memory leaks in test-tool, rather than git itself.

This is a sibling series to my just-submitted series for fixing memory leaks in built-ins[1], but the the two do not textually or semantically conflict.

There are still a few other test-tool memory leaks, but these are the ones I had patches ready for, having focused on trying to get t00*.sh passing first, and then picking some low-hanging fruit after that.

Passing CI for this series can be found at [2].
