Remove redundant check of XDG_CONFIG_HOME

[couldbeanemail]

When checking the config iamb checks XDG_CONFIG_HOME twice.
Once with the dirs dependency. Once on its own. This removes the redundant checks, and the now unused function.

dirs only checks for XDG_CONFIG_HOME on linux. The current version allows to override the config dir with environment variables on all platforms. I'm not sure whether that is intended though.

Afaik MacOS doesn't really support XDG_CONFIG_HOME. Thus it wouldn't really be well defined to support it anyways. There seem to be other mechanisms. See: dirs-dev/dirs-rs#56 dirs-dev/directories-rs#47 (comment) In the case that one would want to pretend that XDG variables work on other platforms, one should remove the call to dirs and make this explicit. best regards :)

Also: the decision should be in line with what is decided in #557 or vice versa. I think the same logic would apply there, but I am aware that people have different takes on this.

This exists because it is needed for folks using nix home-manager on macOS, where xdg.enable can be set to allow managing everything at the XDG config paths, which can then have its files managed by home-manager.
