for the same module name. Other minor fixes:
* Show skipping already installed modules with install action and `-v`.
* Consider external module dirs when calling compile action directly, by
making sure _zimfw_source_zimrc is called first.
* Ignore return value from `zargs` with `-P`, as it's oddly returning
123 since Zsh 5.9. Maybe related to these changes:

Fix computing the list of unused modules by using the full `_zdirs`
instead of just the `_zmodules` names. The fixed code was even simpler
and cleaner, which makes it even more satisfying. :- )
Show "not found" instead of "not installed" error when an external
module dir does not exist, since we don't install external modules.
Using the `list` action with `-v` shows all current details for the
existing modules.
Don't try to install or update external modules, since they have an
absolute path instead of a valid URL.
