Regular monthly update; BTW, it is now failing as below:

@saschagrunert Oh no it is not good now because compile failed with gts :-(

I found that they did some changes with NixOS/nixpkgs@b935375#diff-27c5ecf00b5c424626270f66620413ea9dc7bac44cbf965e3b3d2eb5a7c9f393 but I have no idea yet for how to overcome it ?_?

This PR introduce 3 changes:

• Upgrade Nix stable channel from 20.03 to 20.09.

  NixOS 20.09 released at 2020-10-27, see
  https://nixos.org/manual/nixos/stable/release-notes.html#sec-release-20.09
  for more information.

• Replace git with gitMinimal.

  All 6 projects (i.e. crun/conmon/skopeo/buildah/podman/cri-o) are
  having git as dependency for failsafe during bootstrap. BTW
  [20.09] git: 2.28.0 -> 2.29.2 NixOS/nixpkgs#104896 replace asciidoc
  with asciidoctor so trigger the dependency chain to glib and so
  failed (see below). Switching to gitMinimal skip this dependency
  chain to glib, which also speed up overall build process.

• Adding -pthread for glib

  conmon couldn't skip the error by replacing git with
  gitMinimal since it do depend on glib. Since glib trigger
  error message "undefined reference to 'pthread_create'", therefore
  adding pthread to CFLAGS could solve the problem.

Also see:

• Update nix pin with make nixpkgs crun#550
• Update nix pin with make nixpkgs #218
• Update nix pin with make nixpkgs skopeo#1120
• Update nix pin with make nixpkgs buildah#2831
• Update nix pin with make nixpkgs podman#8526
• Update nix pin with make nixpkgs cri-o/cri-o#4395
