What

In the stellar-cli derivation in the nix flake, pkg-config was moved from buildInputs to nativeBuildInputs.

Why

Prior to this change, the stellar-cli derivation fails to build on NixOS systems as pkg-config fails to find openssl when building. pkg-config provides a setup-hook that requires pkg-config to be in nativeBuildInputs. This setup-hook will look for derivations in buildInputs with a pkgconfig derivation. With this change, the derivation builds as expected. This kind of issue was also discussed in this forum thread.

  Could not find openssl via pkg-config:
  Could not run `PKG_CONFIG_ALLOW_SYSTEM_CFLAGS=1 pkg-config --libs --cflags openssl`
  The pkg-config command could not be found.

  Most likely, you need to install a pkg-config package for your OS.
  Try `apt install pkg-config`, or `yum install pkg-config`,
  or `pkg install pkg-config`, or `apk add pkgconfig` depending on your distribution.

  If you've already installed it, ensure the pkg-config command is one of the
  directories in the PATH environment variable.

  If you did not expect this build to link to a pre-installed system library,
  then check documentation of the openssl-sys crate for an option to
  build the library from source, or disable features or dependencies
  that require pkg-config.

  cargo:warning=Could not find directory of OpenSSL installation, and this `-sys` crate cannot proceed without this knowledge. If OpenSSL is installed and this crate had trouble finding it,  you can set the `OPENSSL_DIR` environment variable for the compilation process. See stderr section below for further information.

  --- stderr


  Could not find directory of OpenSSL installation, and this `-sys` crate cannot
  proceed without this knowledge. If OpenSSL is installed and this crate had
  trouble finding it,  you can set the `OPENSSL_DIR` environment variable for the
  compilation process.

  Make sure you also have the development packages of openssl installed.
  For example, `libssl-dev` on Ubuntu or `openssl-devel` on Fedora.

  If you're in a situation where you think the directory *should* be found
  automatically, please open a bug at https://github.com/sfackler/rust-openssl
  and include information about your system as well as this message.

  $HOST = x86_64-unknown-linux-gnu
  $TARGET = x86_64-unknown-linux-gnu
  openssl-sys = 0.9.107


  It looks like you're compiling on Linux and also targeting Linux. Currently this
  requires the `pkg-config` utility to find OpenSSL but unfortunately `pkg-config`
  could not be found. If you have OpenSSL installed you can likely fix this by
  installing `pkg-config`.

@juliankuners it need to be rebased, so given it was a small feat, I just did it myself.
