Subject: [PATCH] lambda-mod-zsh-theme: add hooks and patch shebangs

This ensures that no impurity exists due to implicitly depending
on`/usr/bin/env`.

It stores the theme into `$out/share/zsh/themes` to make it possible to
find theme using `buildEnv` and remain consistent with other ZSH
extensions.
