    Revert patching _syscmd_uname
    
    The commit: Ic48aed13d9ce262cb0d06ccc1d7c79f2fd2a365a patched
    _syscmd_uname in an attempt to ease development on MacOS X, however,
    this non-public function was removed from Python 3.9, and now, tests
    are failing with this version of Python.
    
    Therefore, this patch removes the hack and restores sanity.
