    Don't freeze full executable paths at load time
    
    It's bad practice to use `executable-find` in defcustoms, because the
    value will be expanded into a fully-qualified path at the time the
    file is loaded, using whatever is the effective `exec-path` at the
    time. This can lead to confusion if the file is somehow loaded before
    a user deliberately sets up his path.
    
    When only an executable name is used, as is the case with this change,
    it is looked up in the $PATH at the time it is used, which reliably
    leads to expected behaviour. And the user can of course still
    customise any `nix-*-executable` variable to a full path if they wish.
