setools is no longer hosted on https://github.com/TresysTechnology/setools/.
Update the source location to its new home,
https://github.com/SELinuxProject/setools/.
Refresh patches 0001-remove-werror-flag-from-setup.patch and
0002-Do-not-export-use-setools.InfoFlowAnalysis-and-setoo.patch for
4.3.0 and remove patch 0003-setup.py-drop-path-prefix-from-man-install.patch
that is now upstream.
Add a new dependency on host-python-cython, as setup.py now depends on
it.
