chore(nixpkgs): Bump channels to 2021-05-25 r/2630

* users/grfn/system/home/yeren: remove obsolete awscli2 overrides

* ops: make new isSystemUser || isNormalUser assertion happy

* users/grfn/system/system/mugwump: make buildkite agents system users

* users/tazjin/nixos/camden: set isSystemUser = true for git

* users/tazjin/emacs: Remove missing & broken packages

* third_party/openldap: remove, as the argon2 module is now enabled upstream

* third_party/gerrit_plugins: Pinned new unstable hashes

* third_party/nix, third_party/grpc: Disabled CI as these are broken

* third_party/overlays/emacs: Bumped version to stay in sync with channel

* third_party/buzz: Update LIBCLANG_PATH to reference libclang.lib,
  since libclang's default output no longer contains libclang.so

* users/grfn/system/home: Install julia-stable instead of julia (which
  aliases to julia-lts), as the latter depends on an insecure version of
  libgit
