    gnu: python-cffi: Improve package style.
    
    * gnu/packages/libffi.scm: Add python-build and pyproject
    modules. Select just pypi-uri symbol from python module.
    (python-cffi): Fix indenation and adjust order of fileds.
    [build-system]: Swap to pyproject-build-system.
    [arguments]<test-flags>: Move tests directories and deselcect options
    here.
    <phases>: Use default 'check phase. Add 'set-gcc phase.
    [native-inputs]: Add python-setuptools and python-wheel.
