gnu: python-pyzmq: Update to 27.0.1.

The project does not ship bundled source of zeromq and cythonized files,
instead it use <buildutils/bundle.py> to ship as a build option relying
on system libraries.  The build is controlled via CMakeLists.txt.

* gnu/packages/python-xyz.scm (python-pyzmq): Update to 27.0.1. Use G-expressions.
  [source] <snippet>: Remove all as no longer required.
  [build-system]: Use pyproject.
  [arguments] <configure-flags>: Remove as no longer required.
  <phases>: Remove 'build-extensions and replace by 'delete-source which
  is chepper than to rebuild it once again; use default 'check.
  [inputs]: Add libsodium.
  [native-inputs]: Remove pkg-config, and python-tornado-6; add
  cmake-minimal, python-packaging, python-scikit-build-core, and
  python-tornado.
