zsh: use a custom command for fzf ZLE widgets
Notable differences to the default command shipped with fzf:
- I want to see hidden files, but not directories (the default hides
both).
- I want to exclude some directories on my Mac home, which are too
large and make the find command really slow. Plus, I never want to
dig into those directories with this method anyway.
