pythonPackages: improve layout
- Move the creation of the joinmarket Python pkgs from
  `joinmarket/default.nix` to `pkgs/python-packages/default.nix`.

- Move definitions of old pkg versions from the main Python pkgs
  to the joinmarket Python pkgs.
  These old versions are only required by joinmarket.
