Fixes #6157

`${var:t:h}` uses:

- `${var:t}` which acts as `basename`.

- `${var:r}` which removes the extension.

See http://zsh.sourceforge.net/Doc/Release/Expansion.html#Modifiers

Cause unrar to preserve directory structure. (Why is only unrar different?!)

Removed the assignments to fpath as well, since that's all handled in the .oh-my-zsh/oh-my-zsh.sh boot script.

Removed calls to compinit in the extract and the bundler plugins. compinit should only be called once, after all modules, libs, etc are imported.
