specialization: fix name conflict inside NixOS module (#3718)

Browse source 
If used inside the NixOS/nix-darwin module, we get conflicting definitions
of `name` inside the specialization: one is the user name coming from the
NixOS module definition and the other is `configuration`, the name of this
option. Thus we need to explicitly wire the former into the module arguments.
