home-manager: check FQDN for '--flake .' attribute

Browse source 
Since nixpkgs commit 993baa587c4b82e791686f6ce711bcd4ee8ef933,
`networking.hostName` is not allowed to be a FQDN.

Add `hostname --fqdn` to the default flake attribute names that are
searched.

If

    netorking.hostname = "hostname";
    networking.domain = "example.com";

is set in the system NixOS configuration, this allows defining

    homeConfigurations."username@hostname.example.com" = ...

and still use

    home-manager switch --flake .

instead of having to type out

    home-manager switch --flake .#$(whoami)@$(hostname --fqdn)
