Subject: [PATCH] podman: fix cross compilation build

- See `Nixpkgs` issue 467994 for detailed build logs showing the
  failure.

- `Podman` will use its vendored version of `go-md2man` when the
  `GOMD2MAN` environment variable is unset.

- When cross compiling from `x86_64-linux` to `aarch64-linux`, this
  results in the tool being compiled with the `aarch64-linux` compiler
  using `x86_64-linux` options. The compiler arch is wrong, so the build
  fails.

- To circumvent this use `Nixpkgs` version of `go-md2man`.

- The current vendored version matches `Nixpkgs` version (v2.0.7):
  https://github.com/containers/podman/commit/7e14a0340922a03781f9f6238a914b04a749573f

- The reason for the vendoring is detailed in this commit:
  https://github.com/containers/podman/commit/dfec510b41b536d4a3afc810cab335d1d0feb3e0
