maintainers: Fix duplicate values

@patricksjackson -> @arcuru was done in
https://github.com/NixOS/nixpkgs/pull/263460, but
https://github.com/NixOS/nixpkgs/pull/240329 accidentally undid it

@DomesticMoth -> @asciimoth was done in
https://github.com/NixOS/nixpkgs/pull/203290, but the old entry wasn't
dropped

The nix@pdtpartners.com email is used by three users. According to
@mupdt, `nix+<github hadle>@pdtpartners.com` should work instead: https://github.com/NixOS/nixpkgs/pull/488851#issuecomment-3884975021
