zsh: change implementation of tt

In zsh, an EXIT trap defined in a function runs on that function's
execution end. Unfortunately, that's not what I want! Instead, there's
the zsh hook zshexit, but that takes a function.

This changes tt to add the generated directories to a deduplicated
array, which is cleaned up on exit, as long as the function has been loaded.
